Question

Accirding to band theory what are differences between conductor and semi conductor​

Answer 1

Answer:

• The main difference between the conductor, semiconductor & insulator is in its conduction state. The conductors always conduct electric current while the insulators do no conduct. However, semiconductor conducts & blocks at different condition.

• The conductor has a large number of electrons for transmission, whereas semiconductor has a very little number of electrons for transmission. The temperature coefficient of a conductor is positive, whereas semiconductor has negative. The conductor doesn't have forbidden gap whereas semiconductor has forbidden gap.

hope it works...

Answer 2

Explanation :-

In a conductor, there is partially filled valence band or there is overlapping between valence band and conduction, whereas in a semiconductor there is small energy gap between valence band and conduction
