采用LLP变分法研究了抛物量子阱中极化子的Rashba效应,得到了极化子基态能量的表达式,并讨论了半阱宽及波矢与基态能量之间的关系.结果显示,基态能量是半阱宽和电子-声子耦合强度的减函数,而是波矢的增函数.由于Rashba效应基态能量零自旋轨道分裂成两支. The LLP variational method is used to study the Rashba effect of the polaron in a parabolic quantum well. The expression of the ground state energy of the polaron is obtained, and the relationship between the half-well width and wave vector and the ground-state energy is discussed. The energy is a decreasing function of the half-well width and the electron-phonon coupling strength, but an increasing function of the wave vector, due to the Rashba effect splitting the zero-spin orbit of the ground state energy into two branches.
