极性晶体膜中的磁极化子的能谱

The Energy Spectrum of A Magnetopoiaron in a Polar Crystal Slab

本文计及了纵光学声子和面光学声子,利用 Haga 的方法,得到了极性晶体膜中磁极化子的能谱.并讨论了朗道能级的修正与磁场和膜厚的关系.数值计算表明,当膜极薄时膜中磁极化子呈现为二维的特征;在随着膜厚的增加,磁极化子性质趋向三维的情形.

Including bulk longitudinal—optical and surface—optical phonons,the energy spectrum of a magnetopolaron in a polar slab is derived.The rela tions of its correction of Landau level to the magnetic field ands lab width are studied.
