A) Pure Si doped with trivalent impurities gives a p-type semiconductor
B) Majority carriers in a n-type semiconductor are holes
C) Minority carriers in a p-type semiconductor are electrons
D) The resistance of intrinsic semiconductor decreases with increase of temperature
Correct Answer: B
Solution :
p-type semiconductor are obtained by adding a small amount of trivalent impurity to a pure sample of semiconductor (Ge). Majority charge carriers?holes Minority charge carriers?electrons n-type semiconductor are obtained by adding a small amount of pentavalent impurity to a pure sample of semiconductor (Ge). Majority charge carriers?electrons. The resistance of intrinsic semiconductors decreases with increase of temperature.
