Confined and interface polarons in cylindrical nanowires in an electric field

The effect of an electric field on the basic parameters of confined and interface polarons in cylindrical nanowires embedded in a non-polar matrix are studied theoretically for the first time. Analytical expressions for the quasi-one-dimensional Fröhlich polaron self-energy and effective mass are obtained as functions of wire radius and strength of the electric field applied perpendicular to the wire axis, which may be of use at the interpretation of optical phenomena related to polaron motion in cylindrical nanowire, when the effect of an applied electric field competes with the size quantization.
