摘要：

We consider one dimensional coupled classical-quantum models for quantum semiconductor device simulations. The coupling occurs in the space variable: the domain of the device is divided into a region with strong quantum effects (quantum zone) and a region where quantum effects are negligible (classical zone). In the classical zone, transport in diffusive approximation is modeled through diffusive limits of the Boltzmann transport equation. It can lead to an energy-transport model, obtained using a Spherical Harmonic Expansion model as intermediate step. The quantum transport is described by the Schrodinger equation. The aim of this work is to focus on the derivation of boundary conditions at the interface between the classical and quantum regions. Numerical simulations are provided for a resonant tunneling diode with the energy-transport model.
