抄録

<p>In this study, the electronic band structure of dumbbell-shape graphene nanoribbon (DS-GNR) is calculated by the first-principles calculations performed by density functional theory (DFT). The DS-GNR is consisted of two GNRs with different width connected to each other directly. Therefore, the electrodes and sensing part of DS-GNR has only carbon atoms which are beneficial to enhance the performance of electronic devices. The change of electronic band structure on DS-GNR is considered by the combination of the ribbons of electrodes and sensing part. Furthermore, the orbital distribution of DS-GNR is also changed from that of single graphene nanoribbons (S-GNR). Hence, the dominant factors of the localized orbital distribution are also examined in this study.</p>
