What is depletion region in a p – n junction?
The depletion region in a p-n junction is the area near the junction where free electrons and holes recombine, leaving behind fixed ions. This creates an electric field, prevents further charge carrier movement, and acts as an insulating barrier. For more visit here: https://www.tiwariacademy.com/ncRead more

What is doping?
Doping is the process of intentionally adding impurities to a pure semiconductor to increase its conductivity. These impurities introduce free electrons (n-type) or holes (p-type), altering the material's electrical properties for specific applications. For more visit here: https://www.tiwariacademyRead more

What is an extrinsic semiconductor?
An extrinsic semiconductor is a material whose electrical conductivity is enhanced by doping it with impurities. These impurities introduce free electrons (n-type) or holes (p-type), significantly increasing charge carrier concentration compared to a pure, intrinsic semiconductor. For more visit herRead more

What happens to the width of depletion layer of a p – n junction when it is (i) forward biased, (ii) reverse biased?
(i) In forward bias, the depletion layer's width decreases as the applied voltage reduces the junction's potential barrier, allowing charge carriers to flow. (ii) In reverse bias, the depletion layer's width increases as the applied voltage strengthens the junction's potential barrier, preventing cuRead more

Why is the conductivity of n-type semiconductor greater than that of the p-type semiconductor even when both of these have same level of doping?
The conductivity of an n-type semiconductor is greater than that of a p-type because electrons, the majority carriers in n-type, have higher mobility than holes, the majority carriers in p-type, even with the same doping level.
