Definition of ultrasonic waves: Ultrasonic waves are acoustic waves whose frequency is more than 20kHz .They travel with the speed of sound. Hence their wave
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
Dear Friends, we have already discussed laser, different types of laser, and how a hologram is formed. Today we will discuss about why a laser
Hello Friends, In one of my articles, I have discussed holograms, how a hologram is made and what is holography? Today, we will discuss two
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
In last article I have started discussion on extrinsic semiconductor. In today’s article I will discuss the extrinsic semiconductor and its 2 types in detail.
