Trivalent impurities such as Boron (B), Gallium (G), Indium(In), Aluminium(Al) etc are called acceptor impurity....
WebbA p-type semiconductor is formed by adding a III group element (such as B, Al) as a doping element. An impurity added creates a vacancy of electrons. For example in the above picture, The impurity atom is surrounded by four silicon atoms. It provides the atoms to make only three covalent bonds as it has only three valence electrons. Webb9 juni 2024 · The process of adding an impurity into the semiconductor to increase its ability to conduct electricity is known as doping and the impure semiconductor is known as a doped semiconductor. There are two types of doped semiconductors - the n-type semiconductor and the p-type semiconductor.
