Vedclass · Answer

(B) In a $p$-type semiconductor,trivalent impurity atoms (acceptor atoms) are added to the intrinsic semiconductor. These acceptor atoms create a large number of holes in the valence band. At room temperature,thermal excitation also generates some electron-hole pairs. However,the concentration of holes $(n_h)$ due to the acceptor atoms is significantly higher than the concentration of thermally generated electrons $(n_e)$ in the conduction band. Therefore,in a $p$-type semiconductor,the number of holes in the valence band is greater than the number of electrons in the conduction band $(n_h > n_e)$.
