Abstract:

The properties of strong-coupling polaron in a semiconductor quantum well are studied for the first time by using linear combination operator and variational method. The relations between the vibration frequency, the ground state energy and the self-trapping energy of the strong-coupling magnetopolaron in an infinite quantum well with the well width and the cyclotron resonance frequency are derived. Numerical results of the RbCl quantum well show that the vibration frequency ,the ground state energy and the self-trapping energy of the strong-coupling magnetopolaron will increase with increasing the resonance cyclotron-frequency; the vibration frequency and the self-trapping energy will increase with increasing the the well width, but the ground state energy will decrease with increasing the well width. When the well width is small, the quantum size effect is significant.
