Superconductivity is an advantageous property observed in some materials, which entails an electrical resistance of zero at ...

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 ...

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 ...

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 ...

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics ...

One of the most exciting device functions, the diode (or rectification) behaviour was first envisioned by Aviram and Ratner 1. The Aviram–Ratner molecular diode consists of a donor and an ...
