摘要
在量子环中电子与体纵光学声子强耦合的情况下,通过求解能量本征方程,得出了电子的第一激发态和基态的能量及其波函数.数值计算结果表明自由旋转品质因子随量子环内径(或外径)的增大而减小,且随电子-声子耦合强度的增大而增大.
On the condition of electron-LO-phonon strong coupling, the eigenenergy and eigenfunction of the ground state and the first excited state of the electron in quantum ring are obtained by solving precisely the time-independent Schrodinger equation. Numerical calculations indicate that the quality factors of free rotation decreases with increasing the inner radius (or outer radius) of the quantum ring, and it increases with increasing the electron-LO-phonon coupling strength.
