The process for the formation of an n-type and a p-type semiconductor is to be determined. Concept introduction: Band theory is a model that defines the energy of the electrons in the solid and determines the conductivity of the solids. It is derived from the theory of the molecular orbital. The lower occupied molecular orbital is known as valence band and higher unoccupied molecular orbital are known as the conduction band. The solids can be classified on the basis of band theory as follows: 1. Conductors. 2. Semiconductor 3. Insulators Semiconductors are metalloid and have less energy difference between the valence band and conduction band. The electrons move from valence band to conduction band when potential is applied and the current follows through the semiconductor.
