A hydrodynamic approach based on velocity and energy conservation equations is developed and used for the simultaneous evaluation of the electronic steady-state transport in an n+nn+ SiC structure. An original decomposition of velocity and energy profiles along the structure in terms of field, convective and diffusion contributions is presented. Monte Carlo simulation of electron transport in this device has also carried out. The anode voltage ranges from 10 to 50 V. The distributions of electron energies and electron velocities, and the profiles of the electron density, electric field and average electron velocity are computed. Based on these data, the excellent agreement of the hydrodynamic approach with Monte Carlo simulations is discussed.
