We study the application of the mixed finite elements method (MFE) for the bidimensional simulation of the simplified hydrodynamic and energy-transport models. The two main points are the use of entropic variables which gives a symmetric positive definite problem and a coupled computation of the equations for electrons which requires a generalization of the MFE method for vector valued problems. We give numerical results on JFET and HEMT devices.
