$p$-type semiconductor

Vedclass · Answer

(A) In the given energy band diagram,we observe the presence of an energy gap $E_g$ between the valence band $(E_V)$ and the conduction band $(E_C)$. This indicates that the material is a semiconductor.Looking closely at the diagram,we see that there are more holes (represented by open circles) in the valence band than electrons (represented by filled circles) in the conduction band. Specifically,the presence of acceptor energy levels just above the valence band is characteristic of a $p$-type semiconductor,where holes are the majority charge carriers.Therefore,the material is a $p$-type semiconductor.

In the energy band diagram of a material shown below,the open circles and filled circles denote holes and electrons respectively. The material is a/an
