摘要
An outstanding problem of a quantitative description of electronic properties of a vertical gated quantum dot has been solved by a self-consistent approach to the Poisson and Schrodinger equations. We have calculated the confinement potential and determined the conditions for single-electron tunneling. A good agreement with experiment has been obtained for the 12 single-electron current peaks as a function of gate voltage V-g for source-drain voltage V-sd = 0, the bounds on diamond-shaped regions in the V-g - V-sd plane, for which the flow of current is blocked; and the current-gate voltage characteristics in an external magnetic field.
