Vedclass · Answer

(C) An $N-$type semiconductor is formed by doping an intrinsic semiconductor with pentavalent impurity atoms. Although the number of free electrons is greater than the number of holes,the impurity atoms themselves are electrically neutral before doping,and the crystal lattice remains electrically neutral after doping. Therefore,the net charge on an $N-$type semiconductor is $0$ (it is electrically neutral).

The net charge on an $N-$type semiconductor is
