Abstract

The property of the remote electron a certain distance away from a Wigner crystallized two-dimensional electron system (2DES) is investigated. The electron mass of the remote electron is: 1) modified by the periodic potential of the Wigner crystal (WC), and 2) renormalized due to the WC phonons, i.e. the polaron effect. The latter is obtained using the Feynman path integral method which also provides us with the correlation energy. In this novel polaron problem the electron-phonon interaction can be controlled by the distance between the two 2DES.
