N-type Semiconductor : Doping, Energy Diagram & Its Conduction

What is P-type Semiconductor? Energy Diagram, Conduction ... In order to form a p-type semiconductor the basic step is to dope intrinsic semiconductor with trivalent impurity. In this type, the valence shell consists of three electrons requires further one more electron. This is possible by sharing the electron. As it is accepting electrons it is generally referred to as acceptor. The acceptor impurities are Boron, indium, gallium. Once these are added to either silicon or germanium p-type semiconductors are formed. Let us take boron as the trivalent impurity so that we can add it to the silicon in order to make it extrinsic. Everything here is completely based on the concept of sharing. The covalent bond concept is preferred during accepting the electrons. Boron atomic number is five. Based on its valence shell electronic configuration concept the numbers of valence electrons present in boron are three. Hence each valence electron forms a covalent bond with the neighboring silicon atoms. The number of bonds formed with a number of silicon at...
