摘要
本文采用Ｈｕｙｂｒｅｃｈｔｓ线性组合算符和变分法相结合的方法，研究了极性晶体膜内电子－声子弱耦合系统的基态能量，得到了作为膜厚和耦合常数函数的极化子的自陷能，对ＧａＡｓ晶体计算了不同支声子与电子相互作用对极化子自陷能的贡献。
The ground state energy of the system, which is the electron - phonons weak - coupling in a polar crystal slab, are studied by means of the linear combination operator and variational method. The change of the self - trapping energy of the polaron changing with the thickness and the coupling constants of the slab is derived. For GaAs crystal slab, the contributions of different branches phonon - electron interaction of the self - trapping energy of the polaron are calculated.
