A particle simulation method is introduced in which two kinds of particle models are used in one device. A conventional Monte Carlo particle model is used in the region where nonstatic effects are evident, and a particle model based on Langevin's equation is used in the region where the drift-diffusion approximation is valid. In this way it is possible to obtain efficiency and the required physical accuracy in device simulation. For the validity of this scheme, a silicon n+ -n-n+ structure is simulated, and some important results are presented
