Abstract
A linear one-dimensional dissipative model is proposed and applied in obtaining numerical simulation results for coupled double quantum dot cells, for single-electron transport dynamics on each cell. Field coupling between cells is modeled simply from a matrix of mutual capacitances. Bistability with only one excess electron on each cell, in a pair of coupled double-dot cells, is demonstrated. Behavior prediction and performance evaluation, for applications such as computational system implementation, are made possible. It is understood from the simulations that balanced dissipation rates are essential for the implementation of optimized single-electron devices, with short settling times.
