| 摘 要： | 采用考虑电子－电子（ｅ－ｅ）相互作用的扩展的紧束缚模型，研究了非简并基态的导电聚合物－－顺式聚乙炔（ｃｉｓ－ＰＡ）的能带结构，发现电子－声子（ｅ－ｐｂ）耦合增强可使其导带底端能极发生劈裂，从而使事隙变窄。

| Abstract: | The energy band structure of nondegenerated polymer-cis-PA has been studied by adopting the extended tight-binding model, which including e-e interactions. It was concluded that the stronger of the e-ph interactions can make the bottom of band gap split, so they lead the band gap to be narrow. |
