Question

Provide the classification of semi-conductors with example.

✓

Answer

→The Semi-conductors can be classified as follows:
(i) Elemental Semi-conductors : $S i$ and Ge
(ii) Compound Semi-conductors :
Example are :
(a) Inorganic : $C d S, G a A s, C d S e, I n P$ etc.
(b) Organic : anthracene, doped pthalocyanines, etc.
(c) Organic polymers : polypyrrole, polyaniline, polythiophene etc.
→Most of the currently available semi-conductor devices are based on elemental semiconductors $S i$ or $G e$ and compound inorganic semiconductors.

A molecule of a substance has a permanent electric dipole moment of magnitude $10^{-29} C m$.
