Simulation of Dissipative Single-Electron Dynamics in Coupled Quantum Wells

A one-dimensional model is developed and numerical simulation results are presented for single-electron tunnelling non-linear dynamics in a pair of coupled quantum dots, with ohmic energy dissipation. The analysis of a simple mesoscopic cell structure with two coupled quantum dots, possessing bi-stability with only one excess electron, is also presented in order to evaluate its application in implementing fast cellular automata.
