“In the case of silicon and germanium, cryogenic temperatures are required for this, which puts the value of this effect under a question, in materials such as diamond and gallium nitride, it can be observed already at room temperatures. This means that this effect can be used for the creation of devices for the mass market," RIA Novosti quoted the MIPT researcher Dmitry Fedyanin as saying.
For several years, a group scientists headed by Fedyanin searched for new sources of light and studied exotic materials that are not used to create LEDs.
MIPT scientists also discovered another effect and proved that a “pure” semiconductor consisting of layers of diamond plates with different types of inclusions could be used to create a powerful solid-state laser.
Experiments have shown that diamond lasers and LEDs are 100 times brighter than conventional multilayer lasers and LEDs.
