Question

write notes on n type and p type semiconductor ?​

Answer 1

hay mate

Answer:

In a p-type semiconductor, the III group element of the periodic table is added as a doping element, whereas in n-type the V group element is the doping element. ... In the n-type semiconductor, electrons are majority carriers, and holes are minority carriers.

Answer 2

Answer:

Explanation:

                  n−Type Semi Conductor

An n-type semiconductor is created when pure semiconductors, like Si and Ge, are doped with pentavalent elements. As can be seen in the image above, when a pentavalent atom takes the place of a Si atom, four of its electrons bond with four neighbouring Si atoms. However, the fifth electron remains loosely bound to the parent atom. Hence, the ionization energy required to set this electron free is very small. Thereby, this electron can move in the lattice even at room temperature.

                             p-type semiconductor

A p-type semiconductor is created when trivalent elements are used to dope pure semiconductors, like Si and Ge. As can be seen in the image above, when a trivalent atom takes the place of a Si atom, three of its electrons bond with three neighbouring Si atoms. However, there is no electron to bond with the fourth Si atom.
