Question

compare metal,insulator & semicondutor​

Answer 1

Answer:

Metals are good conductors of electricity. Insulators are bad conductors of electricity. Similarly,semiconductor devices are partial conductors of electricity means their conductivity lies between conductors and insulators. In case of metals, electrons fill the conduction band partially.

Answer 2

Answer:

Classification of Metals, Semiconductors, and Insulators. In case of metallic conductors, conduction band overlaps on the electrons in the valence band. In insulators, there is a large gap between both these bands. ... Semiconductors have a small gap between both these bands.
