What are intrinsic semiconductors ? |
Answer» Solution : In semi conductors, the gap between the valence band and conduction band is SMALL. Therefore, some ELECTRONS may jump to conduction band and show some conductivity.  Electrical conductivity of semiconductors increases with rise in temperature, since more electrons can jump to the conduction band. Substances like silicon and germanium show this TYPE of BEHAVIOUR and are called intrinsic semiconductors. The conductivity of these intrinsic semiconductors are too low for practical USE. |
