Semiconductor Diodes
A diode is a device that allows current to flow only in one direction. It is made from p-type or n-type semiconductors joined together. It has a depletion layer/p-n junction/potential barrier. How the depletion layer is formed The depletion layer is formed when a p-type and n-type are joined. The electrons in the n-type semiconductor…

Optoelectronics
Optoelectronics deals with the study of all the electrically driven light-emitting devices, all devices which produce electrical effects when exposed to light, and all methods of conducting light through fixed pathways. Photometry units When a current is passed through a light source, a portion of the power dissipated appears in the form of light radiated…
