In terms of band theory, what is the difference (i) between a conduct – InterviewSolution

1.	In terms of band theory, what is the difference (i) between a conductor and an insulator (ii) between a conductor and a semiconductor ?
Answer» Solution :(i) As PER Band.s THEORY, the FORBIDDEN GAP between valance and conduction band in insulator is very large while in conductor, these bands overlap and have no forbidden gap. (ii) The forbidden gap in SEMICONDUCTORS are small while in conductors there is no forbidden gap.
