Question

______is an example of conductor of overlapping bands​

Answer 1

Silicon and germanium are examples of a conductor of overlapping bands​

How conductors overlap bands:

• In conductors, such as metals, the valence band overlaps the conduction band, while in semiconductors, the gap between the valence and conduction bands is so small that it can be filled by thermal or other excitations.

• In insulators, the electrons in the valence band are separated from the conduction band by a significant distance.

• The valence electrons in conductors are virtually free because the conduction and valence bands overlap in these materials.

• Semiconductors are materials whose electrical conductivity falls between that of an insulator and that of a conductor. The valence band of a semiconductor is nearly full, while the conduction band is nearly empty.
