REVOLUTIONARY LIGHT EMITTING SILICON

We use and create much more data every year. But our modern technology, based on an electronic chip, is reaching its peak. The limiting factor is the heat created by the resistance of electrons passing through the current to copper as they connect to the chips of many transistors. If we want to continue to transmit more and more data every year, we need new techniques that do not generate heat. Bring a photon that uses a photon (light particles) to send the data.Unlike electrons, photons are not stable. Because they do not have mass and charge, they are less likely to spread into the material they pass through and therefore do not generate heat. This reduces energy consumption. In addition, by replacing the electrical communication in the visual communication chip, the communication speed on the chip and the chip can be increased by 1000. Data centers will benefit more with faster and faster data transfer. Low power consumption. For the cooling system. But these photo chips will also bring new applications. Consider laser radar for autonomous machines and chemical sensors for medical diagnosis or for measuring air and food quality.The fall of an electron emits a photonYou need a light source to use lighting in brands. Full laser. The main semiconductor material that computer chips are made of is silicone. However, bulk silicone is extremely inefficient in light emission, which has long been believed to play no role in photomontage. Thus, scientists switched to more complex semiconductors, such as French arsenic and Indian phosphate. They are good for light emissions but are more expensive than silicone ones and are difficult to insert into existing silicone microchips.To create a laser compatible laser, scientists need to produce a form of silicone that can emit light. This is precisely what researchers at the University of Endowment Technology (TU / e) have achieved. Together with researchers from Jen, Leeds and Munich, they combined silicon and germanium into a hexagonal structure that can emit light. A significant discovery after 50 years of operation.Hexagonal structureThe key is the so-called gap in the semiconductor group in nature,” said Eric Baxks, lead researcher at TU / e. “When one electron passes from the conduction band to the valence band, the semiconductor emits a photon: light.” If the conduction band and the valence band overlap, so-called photons cannot be emitted at indirect zone intervals – just like silicone. “The 50-year-old theory has shown that silicon in a germanium alloy formed in a hexagonal structure has a direct space between the bands and can therefore radiate.” says Bakkers.Creating silicone in a hexagonal structure is not easy. As Bakers and his team mastered the technique of nanotube development, they were able to make hexagonal silicone in 2015. They formed pure hexagonal silicone from the first nanocardium, which was formed from different materials, the structure of a hexagonal crystal. Then they developed a silicon-germanium shell in this model. Elham Fadal told the first author of Nature, “We were able to build silicon atoms on a hexagonal pattern. From there, they were forced to place silicon atoms in a hexagonal structure.”Silicone laserBut so far they have failed to shine. The Baker team improved the quality of the silicon germanium hexagonal shells by reducing the number of impurities and crystal damage. When fascinated by nanometers with a laser, they can evaluate the performance of new material.
