Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

This project demonstrates how to build a simple latching power switch circuit using an NPN transistor and a pushbutton, powered by a 9V battery. When the pushbutton is pressed, the transistor ...

Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team led by Professor Sungjae Cho in the KAIST Department of Physics ...

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 ...

Power gallium-nitride (GaN) FETs have been available for several years now, but some engineers have been slow to adopt them in power equipment despite their superior characteristics. Getting ...

Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team developed a thickness-controlled black phosphorous tunnel ...
