论文摘要
在$ {\ bf k} \ cdot {\ bf p} $模型中计算出激子与声音声子之间通过变形电位之间的相互作用。评估了基本呼吸模式及其吹式色调以及带有总角动量$ j = 2 $的球体振动的尺寸依赖性。
The interaction between exciton and acoustic phonons via deformation potential in PbS nanocrystals is calculated in the ${\bf k} \cdot {\bf p}$ model. The size-dependence of the Huang-Rhys factors for the fundamental breathing mode and its overtones as well as for spheroidal vibrations with the total angular momentum $j=2$ are evaluated.
