摘 要：Simulation of electronic transport in nanoscale devices plays a pivotal role in shedding light on underlying physics, and in guiding device-design and optimization.The length scale of the problem and the physical mechanism of device operation guide the choice of formalism. In the sub-20 nanometer regime, semi-classical approaches start breaking down, thus necessitating a quantum-mechanical treatment of the electronic transport problem.
