PORTLAND, Ore. — Expensive optical-to-electronic-to-optical converters are needed to switch photonic signals. Now, researchers have demonstrated an excitonic transistor that can perform the operation ...

The transistor and the PWM-switch, the core circuit of power converters, have interesting analogs. Both have three terminals, hence three configurations. They are active devices, and each has a key ...

A single electron makes the difference between "on" and "off" for a new transistor made from a single carbon nanotube, whose minute size and low-energy requirements should make it an ideal device for ...

(Nanowerk News) At Karlsruhe Institute of Technology (KIT), physicist Professor Thomas Schimmel and his team have developed a single-atom transistor, the smallest transistor worldwide. This quantum ...
