When arsenic is added as an impurity to silicon, the resulting material is


Correct option is

n-type semiconductor

Arsenic is pentavalent. The addition each impurity atom makes an extra electron available for conduction. Thus the current carries are mainly electrons. Hence such semiconductors are called n-type semiconductors (n stands for negative current carriers).
