Vedclass · Answer

(C) In an intrinsic semiconductor,at $T > 0 \ K$,thermal energy causes some valence electrons to break their covalent bonds and move into the conduction band,becoming free electrons. This process leaves behind a vacancy in the valence band known as a hole. When an external electric field is applied,these free electrons move in the direction opposite to the field,while the holes effectively move in the direction of the field. Thus,electric conduction in an intrinsic semiconductor is due to the simultaneous movement of both free electrons and holes.
