中文摘要：

采用紧束缚近似模型，运用Green函数和Landauer—Biittiker公式计算了并联型Armchair型边界的石墨烯纳米条带的电子输运性质。结果表明，随着并联纳米条带数量的增加，石墨烯纳米条带电导峰（电导谷）将有相应数量的增加；条带之间的间距增宽，中心区电导谷的宽度将减小。通过数值计算，揭示该新型石墨烯结构电子输运的物理机制，为基于石墨烯的新型器件的设计和优化提供理论指导，并对石墨烯纳米条带在未来集成电路设计中的应用提供理论参考。

英文摘要：

The electronic transport properties of the various graphene structures with parallel armchair graphene nanoribbons （AGNR） have been calculated by using the Green function and the Landauer-Bi~ttiker Formula in tight-binding approximation model. The results show that, the more parallel nanoribbons there are, the more peaks（valleys） will appear in the calculated electri- cal conductivity. When the spacing between the bands is wider, the valley in the center of electri- cal conductivity will be narrower. Our calculation reveals the electron transport mechanism in the proposed structure, provides a preliminary theoretical basis in designing and optimizing grapheme devices, and can be a theoretical reference for the application of graphene nanoribbons in the fu- ture IC circuit layout.
