SEMI CONDUCTOR THEORY
1.1
Introduction We know the importance of using the materials like copper, aluminium etc. in
electrical applications. This is because copper, aluminium etc are good conductors. Similarly, some materials like glass, wood, paper etc. Also, find wide applications in electrical and electronic applications. These are called insulators. There is another category of materials whose ability to carry current, called conductivity, lies between that of conductor and insulators. Such materials are known as semi conductors. Germanium and silicon are two well-known semiconductors.
1.2
Atoms and elements Ordinary matter is made up of protons, neutrons, and electrons and is composed of
atoms. An atom consists of a tiny nucleus made up of protons and neutrons, on the order of 20,000 times smaller than the size of the atom. The outer part of the atom consists of a number of electrons
