The carrier mobility
網頁3. 1. 2 Mobility. The mobility is defined as the drift velocity per unit electric field in a homogeneous semiconductor: ( 313) The carrier mobilities and account for the scattering mechanisms in electrical transport [ 18 ]. Dominant mechanisms are lattice scattering, impurity scattering, and carrier-carrier scattering. 網頁2.2.3 Lifetime and Diffusion Length. So far we looked at (perfect) semiconductors in perfect equilibrium. The density of holes and electrons was given by the type of the semiconductor (as signified by the band gap), the doping, and the temperature. The only other property of interest (introduced in passing) was the carrier mobility – a ...
