摘要
Using the long-time averaged occupation probability method, we study the dynamics of two interacting electrons moving in a one-dimensional array of quantum dots under the action of external electric field. The results show that the dynamical localization can happen perfectly in the quantum dot array with appropriate parameters. These parameters under which localization happens must be selected more strictly when we add more quantum dots in the arrays. (c) 2005 Elsevier B.V. All rights reserved.
