Semiconductor scientists discover effect that was thought impossible

A physical effect known as superinjection underlies modern light-emitting diodes (LEDs) and lasers. For decades this effect was believed to occur only in semiconductor heterostructures. Researchers now have found superinjection to be possible in homostructures, which are made of a single material.
