Two statements are given-one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below.
ASSERTION(A): The electrical conductivity of a semiconductor increases on doping.
REASON: Doping always increases the number of electrons in the semiconductor.
A semiconductor is doped with phosphorous atoms as impurity. The impurity levels created in the semiconductor are close to the
To obtain electrons as majority charge carriers in a semiconductor the impurity mixed is:
What is the difference between intrinsic semiconductor and extrinsic semiconductor?
