Question

state the difference between (1) p-type & N- type material (2) intrinsic vs Extrinsic material explain doping​

Answer 1

Answer:

p-type and n-type materials are simply semiconductors, such as silicon (Si) or germanium (Ge), with atomic impurities; the type of impurity present determines the type of the semiconductor.

The difference between intrinsic and extrinsic semiconductor is that Intrinsic semiconductors are the pure form of semiconductor materials. Whereas extrinsic semiconductors are impure semiconductor formed by adding an impurity to a pure semiconductor.

Doping means the introduction of impurities into a semiconductor crystal to the defined modification of conductivity.

The doped material is referred to as an extrinsic semiconductor. ... Doping is also used to control the color in some pigments.
