Abstract

In this paper, we investigated the influence of electric field on the ground state energy of polaron in spherical semiconductor quantum dot (QD) using modified Lee Low Pines (LLP) method. The numerical results show the increase of the ground state energy with the increase of the electric field and the confinement lengths. The modulation of the electric and the confinement lengths lead to the control of the decoherence of the system.
