| 摘 要： | 本文采用紧束缚近似方法计算了三维电子气系统的集体激发行为。在简单立方、体心立方、面心立方三种结构情形下,提出了一种矩阵表述方法,通过引入矩阵密度关联函数,在无规周相近似(RPA)下有效地处理了系统的等离激元问题。

| Abstract: | The collective excitations of three dimensional tight-binding electron gas system have been studied in the case of three different kinds of structures (s.c.,f .c.c.,b.c.c.). By random phase approximation, we obtain the matrix formulation of the theory. |
