采用线性组合算符和幺正变换方法研究了非对称量子点中强、弱耦合极化子的性质,导出了非对称量子点中强、弱耦合极化子的基态能量和基态结合能随量子点的横向、纵向有效受限长度,电子-声子耦合强度的变化关系。通过数值计算,结果表明,量子点中强、弱耦合极化子的基态能量和基态结合能随量子点的横向、纵向有效受限长度的减小而迅速增大。 The properties of the strong and weakly coupled polarons in asymmetric quantum dots are studied by using the linear combinatorial operator and the unitary transformation method. The results show that the ground state energy and ground state binding energies of the strong and weakly coupled polarons in the asymmetric quantum dots vary with the quantum The lateral length of the point, the length of the effective length in the longitudinal direction, and the change of the electron-phonon coupling strength. The numerical results show that the ground state energy and the ground state binding energies of strong and weakly coupled polarons in QDs increase rapidly with the decrease of QDs and QDs.
