摘要
用简单的几何模型计算了双激子体系的束缚能,得到二维双激子与单激子的束缚能比率随σ=m*e/m*h从0.324到0.228之间变化。
Using a model structure for a two dimensional biexciton,we calculated its binding energy.The ratio of the binding energy of a 2D biexciton to that of a 2D exciton is found to be from 0.324 to 0.228.The results agree fairly well with previous expermental and theoritical results.
