摘要
Electron transport by a potential minimum that moves through a barrier is investigated numerically and theoretically. The integrated electron transfer as a function of the Fermi level has a series of plateaus, each of which corresponds to an integral number of electrons. The accuracy of the quantization depends on the barrier height and can be 1 part in 10(10) or better. The transport mechanism involves nonadiabatic Landau-Zener transitions.
