"WebFor the last decade, numerical simulation of semiconductor devices has evolved a lot. The main efforts have been applied to homogeneous semiconductor devices, particularly to those based on silicon technology (MOSFETs). The models used for these simulations are various and extend from kinetic to drift-diffusion ones (see Markovich et al., 1991). " - Homogeneous semiconductor
