本文计算了GaAs/Al_（1-x）As异质结界面二维电子系统的子带结构。在局域密度泛函近似中考虑了多体交换和关联效应。他们被证明是不重要的，但不是微不足道的小。还计算了光散射谱。结果与现有的实验是合理的协议。
The subband structure of a two-dimensional electron system at a GaAs/AL,-Ga1_xAs heterojunction interface is calculated. Many—body exchange and correlation effects are taken into account in the local density-functional approximation. They are shown to be unimportant but not negligibly small. Spectra of light scatterings are also calculated. Results are in reasonable agreement with existing experiments.
