摘要： 本文计及纵光学声子的色散,在抛物线近似下,计算了极化子的基态能量、有效质量和极化电势,从中发现:随着声子色散的加强,极化子的自陷能变大,有效质量增大,极化电势的屏蔽半径减小.
Abstract: In this paper, the dispersion of the longitudinal optical phonon is considered in a parabolic approxiamation. The ground state energy, effective mass and polarization potential are calculated. Itis found that the more the phonon dispersion, the larger are the self-trapped energy and effective mass of a polaron, and the smaller is the screening radius.
