classification of semiconductors

Classification of semiconductors On the basis of their chemical composition. This scheme divides semiconductors broadly into elemental and compound semiconductors. A. Elemental semiconductors: Si and Ge. B. Compound semiconductors: Examples are: (i) Inorganic: CdS, GaAs, CdSe, InP, etc. (ii) Organic polymers: Polypyrrole, polyaniline, polythiophene, etc. Both elemental and compound inorganic semiconductors are being largely used. … Read more
