摘要
考虑了无限高势垒量子阱,计算得出了零维、一维、二维和三维量子阱中激子-声学声子耦合导致的激子基态能量移动.结果表明,激子的声学极化子效应随材料带宽的增大而增大.
Taking into account the infinite barrier,the energy shift of exciton due to acoustic phonon in the quantum well of 0D、1D、2D and 3D is obtained by numerical calculation.It can be found that the acoustic polaron effect increases with increasing the band width of the material.
