p-type semiconductor A semiconductor that is missing electrons is called an electron hole.

CdS is considered as n-type semiconductor because of the deficiency of sulfur. This creates vacancies with a high electron affinity and causes CdS to acquire electrons easily.
Doping with Group III elements, which are missing the fourth valence electron, creates "broken bonds" (holes) in the silicon lattice that are free to move. The result is an electrically conductive p-type semiconductor.
When pentavalent impurity is added to pure semiconductor, it is known as N-Type semiconductor. In N-type semiconductor electrons are majority carriers where as holes are minority carriers. impurities such as Arsenic, antimony are added. When trivalent impurity is added to pure semiconductor, it is know as P-type semiconductor. In P-type semiconductor holes are majority carriers whereas electrons are minority carriers. Impurities such as indium, galium are added.

A covalent bond exists between an atom of carbon and an atom of fluorine. In this type of bond, the atoms share a pair of electrons to achieve a stable electron configuration.
The majority carrier in p-type semiconductor is the hole. Electron carriers in p-type semiconductor are minority carriers. Minority carriers in any semiconductor are produced mainly by heat. Only at absolute zero temperature would there be no minority carriers.
Everything that exists in the world except for a light ray or an electrical discharge such as lightening is a chemical! A semiconductor is a type of chemical. It is made from elements with valences of 3, 4, or 5.
CdS is considered as n-type semiconductor because of the deficiency of sulfur. This creates vacancies with a high electron affinity and causes CdS to acquire electrons easily.

Secondary emmission
Semiconductor in pure form (i.e. without doping) is called intrinsic or i-type semiconductor. The no of charge carrier in this case is determined by the materials itself only and not by the impurities. In an intrinsic semiconductor number of excited free electron is equal to the number of holes.
