Text Solution
Verified by ExpertsThe correct answer is:
D
The ratio of the pure atoms to impure atoms in extrinsic semiconductors is 
. When pure or intrinsic semiconductors are doped with trivalent or pentavalent impurities then it results in the formation of n-type and p-type semiconductors.
This drastically affects the conduction of these semiconductors and provides free charge carriers to conduct electricity through the crystal.
