Properties of a Weak-Coupling Magnetopolaron in Cylindrical Quantum Dot
柱型量子点中弱耦合磁极化子的激发态性质

The properties of a magnetopolaron with electron-LO-phonon weak-coupling in cylindrical quantum dot,which was in quantum well and parabolic potential,were investigated by using the linear combination operator and unitary transformation methods.Numerical calculations for AgBr quantum dot indicate that the ground state energy,exited states energies and exited energies all increase with increasing characteristic frequency and cyclotron-resonance frequency,and with decreasing cylindrical height,the smaller the cylindrical height is,the faster they increase.Numerical calculation also indicates that excited state energy increases with increasing temperature.These indicate polar of quantum dot is enlarged with increasing confinement of quantum dot,magnetic field strength and temperature.
