The concept of Fermi Level: In simple term, the Fermi level signifies the probability of occupation of energy levels in conduction band and valence band.
Let us discuss today the operation of full wave rectifier: In the full wave rectifier, two PN junction Diodes (say D1 and D2) a connected
Rectifier: A rectifier is a device that converts alternating current into direct current. Half wave rectifier: In this rectifier, the PN junction diode is connected
In a PN junction diode holes are the majority carriers on P side whereas electrons are the majority carriers on n-side. The process of diffusion
To start the discussion of discussion of difference between forward biasing and reverse biasing, first of all let us discuss the meaning of PN junction
Last time we have discussed the conductivity of semiconductor. Let us today derive the expression the expression for conductivity of semiconductor. In a Semi-Conductor
The conductivity of semiconductor can be increased by the following methods: 1. By doping: The addition of impurity atoms to a pure-semi-conductor is known as
Hole in a semiconductor: In a semi-conductor the energy gap is of the order of 1eV. At OK, the semi-conductor behaves like an insulator but
We have already discussed about the concept of semiconductors, their types: intrinsic and extrinsic semiconductors, difference between intrinsic and extrinsic semiconductors and further types of
We have already discussed about the concept of semiconductors, their types: intrinsic and extrinsic semiconductors and further types of extrinsic semiconductors that are n type
