If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs ...
NIST's modified field-effect transistor can count single photons, or particles of light. When light enters through the transmission window (see electron micrograph of top of device), it penetrates ...
