Webconcentration at the interface exceeds the doping density in the semiconductor. This is the strong inversion case in which we have a signiﬁcant conducting sheet of inversion charge at the interface. The symbol ψ is used to signify the potential in the semiconductor measured relative to the potential at a position x deep inside the semiconductor. In 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. Small numbers of dopant atoms can change the … See more The effects of impurities in semiconductors (doping) were long known empirically in such devices as crystal radio detectors and selenium rectifiers. For instance, in 1885 Shelford Bidwell, and in 1930 the German scientist Bernhard … See more Doping a semiconductor in a good crystal introduces allowed energy states within the band gap, but very close to the energy band that corresponds to the dopant type. In other words, See more Group IV semiconductors (Note: When discussing periodic table groups, semiconductor physicists always use an older … See more Conductive polymers can be doped by adding chemical reactants to oxidize, or sometimes reduce, the system so that electrons are … See more 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. … See more Doping during crystal growth Some dopants are added as the (usually silicon) boule is grown by Czochralski method, giving each wafer an almost uniform initial doping.
