摘要：
In the framework of Landau-Pekar theory, we study the polaron problem in the double quantum ring structures within the effective mass approximation in the presence of perpendicular electric and parallel magnetic fields. The electron and polaron ground-state energies are analyzed as functions of external fields and double quantum ring structure parameters. It has been shown that the probability of finding electron in both inner and outer quantum rings can be controlled by barriers and applied fields. (C) 2013 Elsevier Ltd. All rights reserved.
