Types of extrinsic semiconductors

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. As already discussed a doped semi-conductor is known as an extrinsic semi-conductor. It is of … Continue reading

Semiconductor and its types

Semiconductors: Semiconductors are the materials whose conductivity lies between insulator and conductors. Their conductivity lies in between insulator and conductors because of the energy band gap. The energy band gap of semiconductor lies in between insulator and conductors. For example … Continue reading

why insulators do not conduct electricity

In the last article, I have discussed about the conductors, semiconductors and insulators. Today I will discuss why insulators do not conduct electricity or why insulator is insulator? As I have already discussed that there is energy band gap between … Continue reading

Energy Band in a case of Solids

Energy band or energy band gap in solids is defined as the energy gap between the top of the valence band and bottom of the conduction band. The unit of the energy band gap is normally electron-volt (ev). It is … Continue reading

Solids and its types

Solid  Solid is one of the four forms of matter. Solid does not flow like liquids but all the solids possess the property of elasticity which means that when a deforming force is applied on a solid, it returns to … Continue reading
