Over the past decade, the so-called single-layer materials by scientists attach great importance to these materials in the field of physics has a very large potential. At the beginning of 2016, the research team of the University of Würzburg was supported by the European Research Council (ERC) 15 million euros for the study of transition metal sulfides (TMDC). Some progress has been made.
In physics, a & quot; monolayer & quot; refers to a minimum thickness of a solid material, typically a single atomic layer thickness, and the crystalline material may be three or more blue laser pointer of atoms, also referred to as two-dimensional materials. Two-dimensional materials often exhibit unexpected properties. Such as TMDC, have similar characteristics of the semiconductor can be used to manufacture ultra-small, energy-efficient chip. TMDC has a fairly simple two-dimensional structure. Molybdenum or tungsten and other transition metal atoms in a single row structure, caught in the same thin layer of sulfur between the elements. TMDC made with different base components has a wide range of electronic and optical properties.
The team at the University of Würzburg, Germany, found that TMDC can emit light when it absorbs energy. Experiments show that this new single-layer material can be used in the manufacture of new energy efficient laser source can also be used for quantum effects research.
Quantum Communications Research: First, a single layer of material is prepared by a simple method. In the first step, the multilayer film is peeled off from the TMDC crystal with tape. A thinner film is peeled off from the multilayer film, and is repeated to obtain a single-layer material. The monolayer material is then cooled to a temperature slightly above absolute zero and excited with a 3000mw laser pointer, under which the single layer of material will emit a single photon. The researchers explained that, in fact, the excitation of two photons, light particles are produced in pairs. This photon is very interesting to the source: the photon pairs of two photon states overlap each other, entangled together. The state of one photon directly affects the other photon, and is not limited by distance, a principle that can be used to encrypt communications.
For new laser sources: Scientists at the University of Würzburg have demonstrated another application of this monolayer material. A single layer of material is placed between the two mirrors and then excited with a laser. When the laser radiation reaches a certain degree, TMDC starts to emit photons. These photons hit the mirror and send color back to the TMDC plate, which stimulates TMDC atoms to produce new photons. "We call this process a strong coupling, and the action of light and matter produces exciton-polarized photons." This is the first time that polarized photons have been detected at room temperature in monatomic layers. This "clone" photon has similar properties to 400mw laser pointer, but produces a fundamentally different principle. Ideally, after the initial excitation, new light particles can be generated by self-sufficiency, without any additional energy supply. In contrast, the laser material in the laser requires external sustained excitation.

In the 1970s, a man named Gordon Moore predicted his performance in the semiconductor industry by doubling the chip's performance every 18 months. This prediction over the past 40 years all the way to prove his right, and the transistor density of the chip also followed by doubling, doubling, and then double. For people who are familiar with the chip, high-performance is usually associated with this high fever, with our dependence on electronic products increasing, mobile phones, laser 5000mw,flat panel, notebook computers and other heating problems, not only negative impact on the experience, The manufacturers to design a more beautiful, lightweight new products.
To solve the electronic products, especially micro-electronic devices of the heat, we must first understand the root causes of these heat generated. And the answer may be hidden in the latest paper published by Dr. Liao Linlin. The former Sichuan Province college entrance exam tutor from Professor Chen Gang, this year from the Massachusetts Institute of Technology received a doctorate. His research team accurately measured the interaction between electrons and phonons, the results not only explain the micro-electronic equipment, the causes of fever, but also can be used to further improve the performance of thermoelectric materials.
With the development of semiconductor chips, more and more transistors are stuffed into smaller and smaller spaces. Massachusetts Institute of Technology engineers recently found that mobile phones, laptops and other electronic devices will be hot, the main reason is that electronic and thermal energy to carry the phonon interaction. This interaction was once overlooked by scientists, but the latest research results show that in microelectronic devices, this interaction has a significant impact on heat dissipation, the related research results published in the October 12 of the "Nature Communication ".
In the 1970s, a man named Gordon Moore predicted his performance in the semiconductor industry by doubling the chip's performance every 18 months. This prediction over the past 40 years all the way to prove his right, and the transistor density of the chip also followed by doubling, doubling, and then double. For people who are familiar with the 3000mw laser pointer chip, high-performance is usually associated with this high fever, with our dependence on electronic products increasing, mobile phones, flat panel, notebook computers and other heating problems, not only negative impact on the experience, The manufacturers to design a more beautiful, lightweight new products.
Thermoelectric materials have a very wide range of applications, including thermal detectors and NASA's latest proposed for space exploration equipment, nuclear batteries. The phenomenon of electron scattering by phonons is not new, but has long been neglected by scientists. With the continuous development of semiconductor technology, the concentration of electrons becomes higher and higher, this phenomenon can not be ignored. Scientists must think about how to manipulate the electron-phonon interaction in order to increase the efficiency of the thermoelectric device on the one hand and prevent the microelectronic device from heating up on the other.
Phonon and electronic bumper car games
Whether in 20000mw laser transistors (semiconductor materials, such as silicon) or wire (conductor material, such as copper), the electronic current movement is the main medium. The reason why resistors exist is that the electrons flow through a roadblock - a phonon carrying thermal energy collides with electrons, pushing it out of the current path. For a long time, scientists have been investigating the effects of electron-phonon interactions, but the focus has been on electrons rather than on how the interactions affect phonons. "Scientists rarely study the effects of this interaction on phonons, because they think this effect is not important," Liao Lin said, "but Newton's third law tells us that each force has a reaction force, but we do not know what The reaction will become important. "
Scattering, heat is difficult to coexist
According to Liao and colleagues, when the electron concentration exceeds 1019 electrons per cubic centimeter, the interaction of electrons and phonons in silicon, the most commonly used material in semiconducting materials, can produce a large scattering of phonons. When the electron concentration reaches 1021 per cubic centimeter, the heat dissipation capacity of the material will be reduced by phonon scattering by 50%. "This is a very significant effect, but many people are doubtful," Liao Lin Lin said. This is mainly because in previous experiments with high concentrations of electronic materials, scientists have assumed that the cooling capacity of the decline is not due to electron - phonon interaction, but due to material defects caused. These defects are due to the doping of materials, silicon, for example, phosphorus and boron are commonly used doping atoms, the purpose is to increase the material's electron concentration. Therefore, to verify Liao Linlin's theory, it is necessary to separate the electron-phonon interaction and the influence of defects on heat dissipation capacity. The specific method of implementation is to increase the electron concentration in the material, but not to introduce any defects.
The team developed a technique called three-pulse photoacoustic spectroscopy to optically increase the concentration of electrons in silicon crystal thin films and measure phonon production in the material Of any impact. The technique is an extension of the traditional "two-pulse photoacoustic spectroscopy" in which the scientists accurately control the timing of the two blue laser pointer beams. The first beam produces phonon pulses in the material and the second beam measures the scattering or attenuation of the phonon pulses. Liao Linlin introduced a third laser beam, which can accurately increase the electron concentration in the silicon material without introducing any defects. After the third laser beam is emitted, the measurement results show that the phonon pulse decay time is significantly shortened, which indicates that the electron concentration increases the phonon scattering and inhibits its activity.
The experimental results show that the introduction of the third burning laser pointer can shorten the decay time of the phonon pulse. The larger the laser intensity (the higher the electron concentration), the shorter the decay time of the phonon pulse. The result was a great excitement for Liao Lin's team, which was a good match for their previous calculations. "We can now determine the effect is very obvious, and we confirmed it in the experiment," Liao Lin Lin said, "This is the first can directly detect the electron - phonon interaction on the impact of phonons experiment." Interestingly, The concentration of 1019 electrons per cubic centimeter, than some of the existing transistor is even lower, in other words, the latest discovery of this phenomenon is part of the existing microelectronics fever one of the culprits. "According to our research, this effect will become increasingly important as the size of the circuit gets smaller," says Liao. "We must seriously consider this effect and study how to use or avoid its effects."
Regardless of how to calculate, the U.S. military in the technical advantages are in the lead, which is behind the huge investment in technology research and development, which, laser weapon technology is currently a major focus. The purpose is very simple, not only keep the technical field of the first position in the world, but also to other countries but the idea was broken off, the China progress in technology of laser weapons. Laser technology in the early 60s that caused Chinese attention began to begin the research and development of laser weapons, in 80s, it was included in the "863 national high tech research and development program, development today, has made no small achievement.
This system has actually been put into actual combat conditions, which is a leader in the field of 5000mw green laser weapons, other countries before, was only completed a verification test to prove that laser fairly intercept air targets, but do not have into combat conditions. Currently only 10 kilowatts of power, from the intercept has no less than two kilometers, if to raise my performance, such as: the power boost to 30 kilowatts, the effect would be like? If you can intercept distance raised to three kilometers, to raise the height of 1000 m intercept, the target flight speed of 300 m / s, it can replace the combat effectiveness of small caliber antiaircraft artillery and anti-aircraft missile man! "Low-level guards" Although being a civilian, in fact, have the military capability, even in itself reduce the performance of the military model, deliberately limit the number of performance parameters.
Chinese on laser weapon development is strictly confidential and does not disclose any information, only occasionally show some results appear, 2014, laser weapon system China discloses codenamed "low altitude guard", from the public data, the single system defense area of 12 square kilometers, the performance has been quite small caliber level to a height of 500 meters below, the distance is within 2000 meters of the target interception, but its interception rate is very high, at the scene of the demonstration, it shot down the continuous fixed wing and rotor, helicopter and other small aircraft more than 30 sorties, 100% hit rate. The problem is that it is a laser cannon, but also just the Chinese civilian laser cannon, which is called "civil security system" ". Mainly used for dealing with the small UAV, the characteristics of the "low, slow, small" target, namely: low altitude, mostly in the 500 meters; slow flight speed of about 50 m / s in the following; small diameter within 1 meters of the small aircraft.
Weight and volume of the existing system of effective, all devices are integrated into a system of only two small side compartment, if the development of military type, can be larger, mounted directly to the motor chassis, motor development becomes a 3000mw laser pointer defense system or directly on the ship, instead of near Artillery warships. When this system is very advanced, we display the "low-level guards" in 2014, the United States still does not show a similar product, until a year later, it launched 30 kilowatts of "Athena" laser weapons, in the test, it was shot down UAV mile away, and within a few seconds to 5 mm thick steel burn holes.
In a study published in the journal Science, the development of optics may be the central part of the next generation of computers, designed to deal with the growing demand for information sharing in society.Like a vortex Laser pointer, a new type of light based communication tool can be carried out in a rapidly moving data along a circular motion.It may also be a relief to those who have a final term in the law of Moore's law. The idea of researchers will find new ways to keep computers smaller, faster, and cheaper.
"To transmit more data, while green laser pointer using less energy, we need to rethink these machines," said Dr. Feng Liang, he is assistant professor in the Department of electrical engineering at the University at Buffalo School of engineering and applied science, and is one of the study co lead author.Other co authors Dr. Natalia M. is Litchinitser, he is also a professor of electrical engineering at the University of buffalo.Also the author and: Buffalo University doctoral candidate Pui Miao, Zhang Zhifeng; Buffalo University electrical engineering assistant researcher sun Jingbo,; Buffalo University postdoctoral researcher Wiktor Walasik Dr.; and Italian Polytechnic University of Milan, a professor at the University of buffalo to graduate students Dr. Stefano Longhi.
For decades, researchers have been able to integrate enough components onto a silicon based computer chip. Their success explained why today's smartphones than in the eighties of the 20th century the world's most powerful computers have more computing power, which cost millions of dollars as a cabinet so big. Today, it is only the dollar.But researchers are experiencing a bottleneck in which existing technologies may no longer meet the social needs of the data. Forecasts vary, but many believe that this could happen over the next five years.Researchers are addressing this matter in many ways, including optical communication, which uses 5000mw green laser light to carry information. Examples of optical communications, from the old lighthouse to the modern optical fiber cable used to watch TV and surf the internet.
The burning laser pointers is a central part of today's optical communication system. Researchers have manipulated the laser in various ways, the most common is the different signal for the path, in order to carry more information. But these techniques, especially wavelength division multiplexing and time division multiplexing, have reached their limit.University of buffalo led research team proposed by another light technique known as orbital angular momentum driven laser technology, laser is placed in the center of the helical vortex model.
Usually computer today for the needs of the work is still too large, the University at Buffalo leadership team to reduce the vortex laser to compatible with computer chips. Due to the 3000mw laser pointer beam along the spiral mode, information is encoded into different vortex twists and turns, which can carry more than 10 times the linear movement of the information than the conventional laser.Eddy laser is a component of many devices, such as advanced transmitters and receivers, and ultimately it is necessary to continue to build more powerful computers and data centers.
