Chinese Abstract

当同时考虑温度和磁场的作用时,应用线性组合算符法研究了电子自旋对弱耦合二维磁极化子能量的影响。对GaAs半导体所作的数值计算结果表明,不同方向的电子自旋使弱耦合二维磁极化子的能级分裂为两条。随着磁场的加强,能级分裂得越显著。电子自旋能量与磁极化子能量之比随磁场或温度的增加而增大。

English Abstract

The influence of the electron-spin on the energy of the weak-coupling 2-D magnetopolaron was studied by using the linear combination operator method, when the action of magnetic field and temperature was considered meanwhile. Numerical calculation, with GaAs semiconductor as an example, illustrated that the energy level of the weak-coupling 2-D magnetopolaron was divided into two by the electron-spin with different direction. The split energy level was more marked with increasing magnetic field. The ratio of electron-spin energy to the energy of the magnetopolaron increases with increasing magnetic field to temperature.
