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 correspondingly ...

A laboratory at Purdue University provided a critical part of the world's first transistor in 1947 -- the purified germanium semiconductor -- and now researchers there are on the forefront of a new ...

AF114 germanium transistors and related ones like the AF115 through AF117 were quite popular during the 1960s, but they quickly developed a reputation for failure. This is due to what should have made ...

At the Forschungszentrum Jülich, a new kind of transistor from germanium–tin alloy has been fabricated by scientists. The alloy comes with numerous benefits over traditional switching elements. The ...

The first transistors were point contact devices, not far from the cats-whiskers of early radio receivers. They were fragile and expensive, and their performance was not very high. The transistor ...

An important breakthrough has been reached in the development of energy-efficient electronic circuits using transistors based on germanium. A team of scientists from the Nanoelectronic Materials ...

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 ...

A team of scientists from the Nanoelectronic Materials Laboratory (NaMLab gGmbH) and the Cluster of Excellence Center for Advancing Electronics Dresden (cfaed) at the Dresden University of Technology ...
