STUDY OF ENERGY BAND STRUCTURE OF ONE-DIMENSIONAL CRYSTAL LINE OF DIMERIZED MOLECULE

为探讨具有二聚体结构的LB膜的一维导电机理,本文用格林函数(GF)法对此类晶链的能带结构进行了理论计算和分析,并讨论了二聚性强弱对能带结构的影响,从而为进一步研究该类材料的导电机理提供了一定的基础。

In the study of LB films, many of them display one - dimensional electric conductivity character. In order to explain the mechenism of the electric conductivity, we used Green's Function method to calculate and study the energy band structure of the one - dimensional crystal chain of dimerized molecule.Then rwe discussed the inferences of different dimer content on the energy band.The tesults of his paper will provide certain theoretical basis for further studies on he tvic conductivity mechanism of the one - dimensional dimerized materials.
