Question

Difference between n type and p type semiconductor in tabular form

Answer 1

Difference Between p-Type and n-Type Semiconductor

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.

Trivalent impurity like Aluminium, Gallium and Indium is added in the p-type semiconductor, while in n-type semiconductor Pentavalent impurity like Arsenic, Antimony, Phosphorus, Bismuth, etc. are added.

The impurity added in p-type semiconductor provides extra holes known as Acceptor atom, whereas in n-type semiconductor impurity provides extra electrons and termed as Donor atom.

In a p-type semiconductor, the majority carriers are holes, and minority carriers are electrons. In the n-type semiconductor, electrons are majority carriers, and holes are minority carriers.
