Electronic structure properties of diblock copolymer-(PPP)_m-(PT)_n-
【摘要】 建立了描述二嵌段共聚物 (PPP) m (PT) n 的紧束缚模型 ,研究了基态下均聚物单体对体系电子结构性质的影响 .研究发现可以通过改变均聚物的尺度、配比或界面耦合强度对共聚物能带结构加以调制 .
【Abstract】 A tight binding model describing the diblock copolymer (PPP) m (PT) n was proposed. The effects of the component monomers on the electronic structure properties of the copolymers in the ground states were studied. It is found that varying the scales, ratios and the intensity of interfacial couplings of the components, may modulate the structures of energy levels of copolymers.
