Semiconductor device are electronic components that exploit the electronic properties of Semiconductor materials, principally silicon, germanium and gallium arsenide , as well as organic semiconductors. Semiconductor devices have replaced thermionic devices (vacuum tubes) I'm most applications. They use electronic conduction in the solid state as opened to the gaseous state or thermionic emission in the high vacuum.

TYPES OF SEMICONDUCTORS

1) Intrinsic semiconductor

2) Extrinsic semiconductor
