Question

What are N- type semiconductors? How they are formed ?​

Answer 1

Answer:

N-type semiconductors

An N-type semiconductor is a type of material used in electronics. It is made by adding an impurity to a pure semiconductor such as silicon or germanium.

Formation of N- type semiconductors

To make the n-type semiconductor, pentavalent impurities like phosphorus or arsenic are added. Four of the impurities' electrons form bonds with the surrounding silicon atoms. This leaves one electron free. The resulting material has a large number of free electrons.

Answer 2

Answer:

n-type semiconductor : the semiconductor made by doping of trivalent impurities to pure semiconductor is known as n type semiconductor
