Self-consistent Modeling of Open Quantum Devices

Akis R., Shifren L., Ferry D.K., Arizona State University, US

In this paper, we describe a method of simulating electron transport in semiconductor devices that operate in the quantum regime. Specifically, devices formed in which the electrons are confined to two dimensions (2D) and transport [...]

The Use of a Green’s Function Formalism for the Simulation of Semiconductor Device Performance

Jovanovic D., Motorola, US

Non-equilibrium quantum transport simulation techniques (e.g. the generalized Kadanoff-Baym approach) have been in existence for over 40 years but have only recently become numerically viable for the simulation of semiconductor devices. This paper reports on [...]

Simulation of Wigner Function Transport in Tunneling and Quantum Structures

Jacoboni C., Bertoni A., Bordone P., Giacobbi N., University of Modena, IT

The Wigner-function approach to quantum transport in mesoscopic electron devices is presented. The concept of Wigner paths allows the formulation of a Monte Carlo simulation which is quantum mechanically rigorous and yet very similar to [...]

Complex Potentials, Dissipative Processes and General Quantum Transport

Ferry D.K., Barker J.R., Akis R., Arizona StateUniversity, US

Complex potentials have been used in the past to simulate dissipative processes, but the normal form of a simple constant term of the form t / h i serves only to trap/detrap particles and does [...]
