The transport and current-voltage properties of submicron GaAs MESFET device are calculated firstly based on the nonparabolic effective mass energy band model and Monte Carlo method which includes all major scattering mechanisms. The electron drift velocity, electric field and the non-homogeneity of mobility distribution in device are obtained. The influences of different gate lengths to electron drift velocity and drain current are analyzed.
