抛物量子点中极化子的温度依赖性
Temperature Dependence of Strong-coupling Polaron in a Parabolic Quantum Dot
摘要
Abstract
On the condition of electron-LO-phonon strong coupling in a parabolic quantum dot, we obtained the ground-state energy of polaron by using Pekar type variation method. The relations between the ground energy and the electron-LO-phonon coupling strength, the confinemont length ,the temperature were discussed. The results indicate that the ground energy of polaron in a parabolic quantum dot will decrease with increasing the electron-LO-phonon coupling strength and the confinement length and increase with increasing the temperature.关键词
