Question

The band structure of semiconductors differs from that of metal conductors in that ________
A metal bands are relatively empty while semiconductor bands are nearly full.
B metal bands are nearly full while semiconductor bands are relatively empty.
C metal conduction bands are lower in energy than valence bands while semiconductor
conduction bands are higher in energy than valence bands.
D metal conduction bands are higher in energy than valence bands while semiconductor
conduction bands are lower in energy than valence bands.
E valence bands in metals are either partially empty or overlap with conduction bands
while these bands in semiconductors are separated by a small gap.

Answer 1

answer :

E ) valence bands in metals are either partially empty or overlap with conduction bands
while these bands in semiconductors are separated by a small gap

explanation:

this can be well explained by image .

in metals valence and conduction band both are overlapped . and in semi conductors they are seperated
