The lowly diode, a device with only two leads, can nonetheless do many things. Diodes can detect, rectify, suppress, emit light, detect light, change capacitance, emit microwaves and more.

Laser diodes work on the same principle as the bigger gas lasers. They function as an optical oscillator by stimulating a chain reaction of photon emission inside a tiny chamber. In edge-emitting ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

the term “thermal diode” refers to an electrical diode that’s used as a basic temperature sensor, which a very different function.) Now, a team led by Jonathan Boreyko, associate professor ...

He also derives a second, natural exponent step function from the Schockley diode equation that is less computationally demanding. To implement these models, [Sebastian] chose an Arduino GIGA R1 ...

This Design Idea presents anunusual method of performing theexclusive functions with two resistors,four diodes, and one transistor.The NPN configuration results inthe XNOR operation, and the ...

This could be the first step towards making heat-resistant computers that can function in extremely hot places, like on Venus or deep inside the Earth, without breaking a sweat. A regular diode is ...
