A diode is a tiny component that controls the flow of electricity by allowing current to pass in only one direction. This ...

We might tend to take the word “diode” for granted if we’re thinking of a “diode” as just a two-lead or two-terminal device that gets used in this or that place for this or that purpose. It can become ...

Last week we covered diodes, specifically thermionic and PN junction diodes. But oh, there are more; and they’re special! One of the the most commonly used ‘specialty’ diode would have to be the metal ...

PIN diodes are ideal for transmit-receive (TR) switches because of a favorable blend of cost, size, and switching speed. Although the PIN diode in the transmit (Tx) arm can be connected as either ...

A thermal diode is a two-terminal nonlinear device that rectifies energy carriers (for example, photons, phonons and electrons) in the thermal domain, the heat transfer analogue to the familiar ...

Renowned for its expertise in providing suitable laser diodes for space applications (e.g. in missions such as GAIA, CATS, ...

In collaboration with scientists in Germany, EPFL researchers have demonstrated that the spiral geometry of tiny, twisted ...
