摘要：

We study transport through two ultrasmall quantum dots with discrete energy levels to which a time-dependent field is applied (e.g., microwaves). The AC field causes photon-assisted tunneling and also transitions between discrete energy levels of the dots. Using the Floquet-matrix technique we propose an electron pump consisting of two serially coupled single-level quantum dots with a time-dependent interdot barrier. We compare our results to the recent experiments by Fujisawa and Tarucha. (C) 1997 Elsevier Science B.V. All rights reserved.
