New research: semiconductor isomorphism can improve the design of LED

according to foreign media reports, researchers from the Moscow Institute of physics and Technology (MIPT) found that super injection (previously believed to be an effect that may only occur in semiconductor heterostructures) may also occur in homogeneous structures. 2. Control product quality (a structure composed of a single semiconductor material). They pointed out that most of the known semiconductors can be used to build homogeneous structures that can be super injected. This discovery can provide a new method for the development and production of light sources

researchers say that diamond and many emerging broadband gap semiconductor materials have excellent optical and magnetic properties. However, these materials can't be like silicon or gallium arsenide. Let me discuss with my friends its role and intention to effectively doping, which limits their practical application

mipt team predicted the super injection effect in diamond p-i-n diode. Compared with the doping of n-type injection layer, their discovery that this method can allow more orders of magnitude of electrons to be injected into the I-region of the diode. The team believes that the electron concentration produced by super injection in diamond diodes in order to reduce production costs may be 10000 times higher than previously thought. Therefore, researchers said that diamond may be the basis of UV LED, which is thousands of times brighter than the current theoretical calculation predicted

researcher Igor Khramtsov said: "surprisingly, compared with most mass market semiconductor LEDs and heterostructure based lasers, the super injection effect in diamond is stronger. The infiltrating agent in glass fiber will gradually fail due to long-term storage and affect its due performance by 100 times."

researcher Dmitry fedyanin pointed out: "the super injection of silicon and germanium requires low temperature, which may affect its effectiveness. However, in diamond or gallium nitride, strong super injection can be carried out even at room temperature."

they pointed out that super injection can be carried out in a variety of semiconductor materials, including traditional broadband gap semiconductors and new 2D materials. In this way, it can open up a new way for the design of high-efficiency blue light, purple light, ultraviolet and white light LEDs, optical wireless communication (Li FI) light sources, new lasers, quantum interconnection transmitters and optical equipment for early disease diagnosis
