Abstract:

With Huybrenchts’s linear combination operator and the Lee-Low-Pines(LLP) transformation methods, properties of excited state of strong-coupling magnetopolaron in parabolic quantum wires are studied. The relations of the first internal excited energy, excitation energy and vibration frequency in parabolic quantum wires with the Coulomb bound potential, confinement strength and cyclotron frequency are presented. The numerical results indicate that the first internal excited energy, excitation energy and vibration frequency increase with increasing of confinement strength and cyclotron frequency. The excitation energy and vibration frequency are increasing functions of the Coulomb bound potential. The first internal excited energy decreases with increasing of the Coulomb bound potential.

Key words: optoelectronics, quantum wire, linear-combination operator, bound magnetopolaron, excited state
