in `n` type semiconductor, electrons are majority charge carriers but does not show any negative charge, the reason is

Options

A. electrons are stationary
B. electrons neutralize with holes
C. mobility of electrons is extremely small
D. atom is electrically neutral.

Answer

D

Explanation

The n - type semiconductor region has (negative) electrons as majority charge - carriers and an equal number of fixed positively - charged donor ions. Again , the material as a whole is neutral . That is a reason atom is electrically neutral.
