Influence of speed of polaron on properties of magnetopolaron in quantum dots

Abstract

Abstract:

Effects of speed of polaron on properties of a strong-coupling magneopolaron in a quantum dot are studied by using improved linear combination operator and the unitary transformation methods. Relations of the vibrational frequency, the ground state energy,the effective mass and the interaction energy of a strong-coupling magnetopolaron considering the influence of Rashba effect, which is brought by the spin-orbit interation, in the quantum dots with speed of polaron are derived. Numerical calculations for RbCl crystal are performed and the results show that the vibration frequency ,the ground state energy and the effective mass of the strong-coupling magnetopolaron in a quantum dot will increase with an increasing in the speed of the poloran , and interaction energy of the magnetopolaron decreases.

Key words: optoelectronics, speed of polaron, improved linear combination operator, magnetopolaron, quantum dot
