Abstract
The influence of an external electric field on the quasi-confined and interface Frohlich polaron basic parameters in a wurtzite nitride cylindrical quantum wire embedded in a non-polar matrix is studied theoretically. By using the Lee-Low-Pines variational approach, the dependences of the polaron self-energy and effective mass are obtained as functions of the wire radius and the strength of the electric field. The contributions of different phonon modes to the polaron basic parameters are estimated.
