In the energy band diagram of a material shown below, the open circles and filled circles denote holes and electrons respectively. The material is
an insulator
a metal
an $n$-type semiconductor
a p-type semiconductor.
Solution
In this Band diagram, number of holes in valence band are more as compared to no.number of electrons in the conduction band. So, it is a p-type semiconductor.
