摘要：
We present for the first time a numerical analysis of a novel laterally-coupled quantum dot (LCQD) circuit with integrated quantum point contact (QPC) detectors. Our simulation involves the self-consistent solution of three-dimensional (3-D) Poisson and Kohn-Sham equations, using the Slater's Rule for determining the charging voltage. Detailed results on conduction band profiles, eigenenergy spectra and associated wavefunctions in the dots, sensitivity of the QPC, and stability diagram are discussed for the few-electron charging regime.
