Abstract

The problem of the existence of a polaron induced by a heavy hole under shielding by the free electron gas is discussed. It is shown that a critical length of shielding by the free charge carriers for polaron destruction exists. The characteristic size of the polaron in a conducting substance and the energy of the electron in the polaronic well have been calculated. Both two-dimensional and three-dimensional shielding charge carriers are considered. It is shown that two-dimensional polarons in a system with two-dimensional shielding electron gas may exist in a wide concentration region.
