The use of transistors for switching things ON and OFF is a key feature of proper hacking. The ability for bipolar transistors to turn things ON and OFF is one of the less known uses while transistors ...

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 ...

Have you ever heard of topological insulators? These are exotic materials where electricity flows only on the surface with very little loss. Now, according to IEEE Spectrum, scientists at Harvard have ...

Graphene has already brought us the world’s smallest transistor, a triple-mode, single transistor amplifier and a supercapacitor that can store as much energy as a battery while recharging in seconds.

Light and electrons interact in a complex dance within fiber optic devices. A new study found that in the transistor laser, a device for next-generation high-speed computing, the light and electrons ...
