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…

The Basic Principle of Operation of an Oscillator
An oscillator is the basic element of ac signal sources and generates sinusoidal signals of known frequency and amplitude. The main applications of oscillators are as sinusoidal waveform sources in electronic measurements. Oscillators can generate a wide range of frequencies (from a few Hz to many GHz) as per the application’s requirement. Even though, an…

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…
