摘要
导电聚合物是具有强电子关联的半导体,本文研究了电子关联对电子激发态的影响,求得了计入电子关联后的激发能谱,它与单电子近似下的能谱不同,本文分析了产生这种差异的原因并讨论了和实验的关系。
Conducting polymers are the semiconductors with strong electron correlation. The influenceof electron correlation on excited states of electron has been studied. Based on the considerationof the electron correlation, the excitation spectrum of electron is obtained, which is differentfrom that derived from the single-electron energy band theoy.The origin of such differenceis analyzed.The relation of our theory with the available experiments is also discussed.
