Intrinsic carrier concentration of germanium
WebThe term carrier mobility generally alludes to both electron and hole mobility in semiconductors. These parameters characterize how quickly an electron and/or hole moves through a metal or semiconductor when under the influence of an electric field. WebThe intrinsic carrier concentration is the number of electrons in the conduction band or the number of holes in the valence band in intrinsic material. This number of carriers …
