Abstract
A key concession in nanoscale device modeling is the derivation of transport models able to depict the quantum effects and, at the same time, to be straightforward in computer codes. In this paper, we propose a model for ballistic transport in heterostructure devices within Quantum Hydrodynamic (QHD). The model is numerical implemented using a finite-difference discretization and tested in the case of resonant tunneling diode due to availability of experimental data. Genuine QHD model is a frame in development of a quantum photovoltaic device simulator.
