The transistor laser invented by scientists at the University of Illinois at Urbana-Champaign has now been found to possess fundamental non-linear characteristics that are new to a transistor and ...

Engineers are unveiling an upgrade to the transistor laser that could be used to boost computer processor speeds - the formation of two stable energy states and the ability to switch between them ...

Transistors could switch on and off faster, last longer, and run on lower voltages than tubes.

The idea of using a transistor as a switch is that the transistor is saturated — that is, increasing base current doesn’t make much change in the collector current.

In theory, the hundreds of photons, controlled by the triggering photon, could fan out and switch off hundreds of other transistors in an optical circuit.

Bose-Einstein condensate – a super-cold gas cloud of atoms – could construct atomic transistors with more complex capabilities than electronics ...
