Modern LEDs and lasers have an effect that underlies them and that effect is superinjection. Previously, it was believed that superinjection was only applicable to LEDs and lasers until now. Researchers doing research on homostructures in the Moscow Institute of Physics and Technology have observed these effect on homostructures. That is why they believe there will be rapid development in the area of light sources. It was proposed by Zhores Alferov and Herbert Kroemer that heterostructures could be used to generate wide band gaps because they consist of two or more complementary semiconductors. This would make it possible for the electrons and holes in the middle layer to attain to higher values. That was how superinjection came to birth. Superinjection is the process of allowing semiconductors to emit light due to frequent recombinations of electrons along with their holes which are seen as free charges in any semiconductor setup. That was how modern LEDs and lasers came to be manufactured after the discovery. But recent research has shown that using just one material rather than several materials, superinjection can be achieved. The researchers of this method believe that their method is superior to that of heterostructures.

Key Takeaways:

  • Modern LEDs and lasers were formerly believed to have one effect that characterized them which cannot be found anywhere else and that effect was superinjection.
  • It was proposed in the 1960s that heterostructures which have complementary semiconductors be used as a way for generating wider band gaps.
  • The phenomenon by which semiconductors are able to emit light due to the frequent recombination of electrons and holes is known as superinjection.

“In a research published in February 21 in the journal Semiconductor Science and Technology, Igor Khramtsov and Dmitry Fedyanin from the MIPT discovered that it is possible to achieve superinjection with just one material and most of the known semiconductors can work with the method.”
