【Abstract】 The properties of strong coupling magnetoploron in the semiconductor quantum dot are investigated by the linear combination operator and unitary transformation methods.The results show that the magnetopolaron binding energy decreases with increasing the effective confinement length,enlarges with increasing the electron phonon coupling strength,and enhances with enlarging the cyclotron resonant frequency.Furthermore,the resonant frequency of strong coupling magnetopolaron in the semiconductor quantum dot decreases with increasing the effective confinement length,enlarges with increasing the electron phonon coupling strength,and enhances with enlarging the cyclotron resonant frequency.So the polaronic effects can not be ignored in the semiconductor quantum dot.更多还原
