采用第一性原理计算对哑铃形石墨烯纳米带（DS-GNR）的电子能带结构（带隙）和电子传输特性进行了理论研究，以阐明其电子性能的主要控制因素，以应用于各种智能传感器，该哑铃形石墨烯纳米带由较薄的半导体GNR和两端较宽的金属GNR组成。发现DS-GNR的电子特性根据沿每个部分的宽度方向的碳原子总数、半导体部分的长度、金属部分的宽度等的组合而显着变化。
The electronic band structure (band gap) and electronic transmission properties of dumbbell-shape graphene nanoribbons (DS-GNRs), which consists of a thinner semiconductive GNR and two wider metallic GNRs at its both ends, was theoretically investigated using first-principles calculation to clarify the dominant controlling factors of their electronic performance for their applications to various smart sensors. The electronic properties of the DS-GNR was found to vary drastically depending on the combination of the total number of carbon atoms along the width direction of each portion, the length of the semiconductive portion, the width of the metallic portion, and so on.
