(Nanowerk News) Transistors in computer chips work electrically, but the data can be transmitted more quickly with light. Researchers have therefore been looking for a way to integrate a laser ...

Engineering researchers at the University of Arkansas have fabricated a new semiconductor material—germanium tin deposited in layers on a substrate of silicon—that could be used to build better and ...

(Nanowerk News) Over the past 70 years, the number of transistors on a chip has doubled approximately every two years – according to Moore’s Law, which is still valid today. The circuits have become ...

A new germanium-tin laser could be used to speed data transfers within CPUs and integrate more easily with existing manufacturing processes -- if certain problems with temperature can be resolved.

Scientists at Forschungszentrum Jülich have fabricated a new type of transistor from a germanium–tin alloy that has several advantages over conventional switching elements. Charge carriers can move ...
