Semiconductor Principles - Technical MCQs

Q1:

When is a P-N junction formed?

A in a depletion region

B in a large reverse biased region

C the point at which two opposite doped materials come together

D whenever there is a forward voltage drop

ANS:C - the point at which two opposite doped materials come together

WHEN two opposite dope materials namely N-Type & P-Type material is joined together and recombination/diffusion of carriers occur which forms the P-N Junction or the Depletion Region.
