WitrynaA p-type semiconductor is an type of semiconductor. When a trivalent impurity (like Boron, Aluminum etc.) is added to an intrinsic or pure semiconductor (silicon or germanium), it is said to be a p-type semiconductor. Trivalent impurities such as boron (B), gallium (Ga), indium (In), aluminum (Al) etc. are called acceptor impurity. WitrynaIn semiconductor production, doping is the intentional introduction of impurities into an intrinsic semiconductor for the purpose of modulating its electrical, optical and structural properties. The doped material is referred to as an extrinsic semiconductor. WitrynaExtrinsic semiconductors are semiconductors that are doped with specific impurities.

"WitrynaThese kinds of impurities are called acceptors. In the presence of an electric field, the holes move around the field and hole conductivity occurs. Semiconductors with a predominance of hole conductivity over the electronic are called p -type semiconductors (from the word positive). The main charge carriers in p -type semiconductors are holes.
