WitrynaA semiconductor is a material which has an electrical conductivity value falling between that of a conductor, such as copper, and an insulator, such as glass.Its resistivity falls as its temperature rises; metals behave in the opposite way. Its conducting properties may be altered in useful ways by introducing impurities ("doping") into the crystal structure. WitrynaThe impurity band problem in semiconductors is formulated in terms of the Green function, the calculation of which has been carried out by a graphical method.

The concentration of the dopant used affects many electrical properties. Most important is the material's charge carrier concentration. In an intrinsic semiconductor under thermal equilibrium, the concentrations of electrons and holes are equivalent. That is, In a non-intrinsic semiconductor under thermal equilibrium, the relation becomes (for low doping): where n0 is the concentration of conducting electrons, p0 is the conducting hole concentration, … WitrynaAs with all semiconductor gases it requires a high level of purity – at least 99.999% - and has a wide range of impurities to be detected.
