Semiconductor From Wikipedia, the free encyclopedia Jump to navigationJump to search For devices using semiconductors and their history, see Semiconductor device. For other uses, see Semiconductor (disambiguation). A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. Its resistivity falls as its temperature rises; metals are the opposite. Its conducting properties ..

Drude model From Wikipedia, the free encyclopedia Jump to navigationJump to search Drude model electrons (shown here in blue) constantly bounce between heavier, stationary crystal ions (shown in red). The Drude model of electrical conduction was proposed in 1900[1][2] by Paul Drude to explain the transport properties of electrons in materials (especially metals). The model, which is an application of kinetic theory, assumes that the ..
