Box 1: Criteria for practical optical logic. The electronic transistor and the logic gates based on it have qualitative features that are crucial for systems of any complexity, but very few ...

A couple years back we covered a very impressive transistor logic clock which was laid out so an observer could watch all of the counters doing their thing, complete with gratuitous blinkenlights.

The sandwich transistor was William Shockley's brainchild ... The crystal can conduct in one direction, but not in the other. A positive voltage in the base pulls the electrons across in the ...

most chips today use field-effect transistors wired as CMOS logic, which consume less power (see FET and MOSFET). Bipolar transistors are available as individually packaged discrete components as ...

University of Houston have created an elastic semiconductor with 8.57cm2/Vs charge carrier mobility, and then made transistors, logic and a sensor array from it. Carrier mobility is largely retained ...
