Single Choice
In case of a semiconductor, which of the following statement is wrong
ADoping increases conductivity
BTemperature coefficient of resistance is negative
CResistivity is in between that of a conductor and insulator
DAt absolute zero, it behaves like a conductor
Correct Answer
Solution
At room temperature, a semiconductor has enough free electrons to allow it to conduct current. At or close to absolute zero a semiconductor behaves like an insulator.
