二维晶体中的亚稳电子对态
Metastable electron-pair states in a two-dimensional crystal
摘要：
研究了二维晶体中两个关联电子可能的量子态，发现在两个最低单电子带之间存在一个电子对的亚稳能带。这些亚稳态是电子关联和晶体势强度相互作用的结果。两个成对的电子在相对坐标中被束缚在同一个晶胞中，它们之间的平均距离约为晶体周期的三分之一。此外，我们展示了如何这样的电子对可以稳定在一个多电子系统。
英文摘要：
We study possible quantum states of two correlated electrons in a two-dimensional crystal and find a metastable energy band of the electron pair between the two lowest single-electron bands. These metastable states result from the interplay of electron correlations and the strength of the crystal potential. The two paired electrons are bound in the same unit cell in relative coordinates with an average distance between them about one third of the crystal period. Furthermore, we show how such electron-pairs can be stabilized in a many-electron system.
