1.

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

Answer»

electrons are stationary
electrons neutralize with holes
mobility of electrons is extremely small
ATOM is electrically neutral.

Solution :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.
