Which statement A-D regarding semiconductors is not correct?
A)An undoped semiconductor does not conduct electricity because it has a filled valence band and a vacant conduction band.
B)Doping silicon with phosphorous produces an n-type semiconductor.
C)An n-type semiconductor has electrons in its conduction band.
D)Doping silicon with gallium removes electrons from the valence band to enhance the conductivity.
E)Statements A-D all are correct.

Question

Quizplus · Accepted Answer

All statements A-D correctly describe aspects of semiconductor physics. A) describes the intrinsic (undoped) semiconductor behavior, B) and C) explain n-type doping and its effect, and D) describes p-type doping by introducing holes in the valence band, which also enhances conductivity.
