Acceptor atoms introduced into a pure semiconductor at room temperature:
A)increase the number of electrons in the conduction band
B)increase the number of holes in the valence band
C)lower the Fermi level
D)increase the electrical resistivity
E)none of the above

Question

Quizplus · Accepted Answer

Acceptor atoms introduced into a semiconductor create additional holes in the valence band, as they accept electrons from the valence band, leaving behind holes which increase the hole concentration. This process does not directly increase electrons in the conduction band, lower the Fermi level, or increase electrical resistivity; instead, it enhances the semiconductor's ability to conduct electricity through hole conduction.
