electrically neutral.

Vedclass · Answer

(C) $P$-type semiconductor is formed by doping an intrinsic semiconductor (like $Si$ or $Ge$) with trivalent impurity atoms (like $B$,$Al$,$In$,or $Ga$).Although there is an excess of holes compared to electrons,the number of positive charges (protons in the nuclei of the atoms) is exactly equal to the number of negative charges (electrons orbiting the nuclei).Therefore,the net charge of the semiconductor material remains zero.Thus,a $P$-type semiconductor is electrically neutral.
