Question

which one of the following statement is not true? A) Resistance of an intrinsic semiconductor decreases with rise in temperature B) A p-n junction can act as a semiconductor diode. C) Doping pure silicon crystal with trivalent impurity gives p-type extrinsic semiconductor D) Majority carries in n-type semiconductor are holes​

Answer 1

Option D

MAJORITY CARRIES IN n TYPE SEMICONDUCTOR ARE HOLES

Answer 2

The wrong statement is the “n type has the majority carries as holes in semiconductor”.

Answer: Option D

Explanation:

The majority carriers in n-type of semiconductor devices are electrons. Holes are majority carriers in the p type of semiconductor devices. The holes are minority charge carriers which carries only small amount of charge or current in “n-type semiconductor”. The remaining statements given in the question are true. The carriers refers to the transportation of object “from one place to another”.
