Abstract
By the moment closure of the Boltzmann transport equation the extended hydrodynamic models for electron transport have been derived in Cai et al J Math Phys 53103503 2012 With the numerical scheme developed in Li et al 2012 recently it has been demonstrated that the derived extended hydrodynamic models can capture the major features of the solution of kinetic equations As the application of the models and the numerical scheme proposed therein we in this paper carry out the numerical simulation to investigate the carrier transport in n+nn+ structures by solving the moment system derived from the Boltzmann–Poisson equations Without any additional empirical parameters than that used in directly solving the kinetic equations we obtain numerical results by the extended hydrodynamic models with very satisfied agreement with the solution of the kinetic equations even in case that the length of the channel is as short as 50 nm
