| 摘 要： | 石墨烯纳米带并不是一个完全平整的结构，而是一个准平面结构．为了研究非平整对石墨烯纳米带电子结构的影响，利用紧束缚方法和轨道杂化理论，研究了弯曲对扶手椅型石墨烯纳米带电子结构的影响．计算结果表明：扶手椅型石墨烯纳米带电子性质与弯曲的程度有关，且在高能部分影响较大；当纳米带的宽度一定时，随着弯曲程度的增加，能带的带隙随之增加．

| Abstract: | Graphene sheet had a quasi-planar structure which was not totally flat. To simulate the effect of non-flat by using the tight-binding method and orbital hybridization theory, it was studied the armchair graphene nanoribbons （ A-GNRS ） with bending. The results showed that the bending A-GNRS energy spectra was obviously depend on the curvature, and with certain width, the gap of energy band increased with increase of curvature of the bending A-GNRS. |
