Electronic Transport in the V-Shaped Edge Distorted Zigzag Graphene Nanoribbons with Substitutional Doping

Figure 2

Transmission spectrum, T(E) ((a), (c)) and the device density of states, DDOS ((b), (d)) as a function of electron energy at zero bias voltage. The results are shown for a pristine graphene ribbon as a reference (a) and a distorted graphene ribbon (c) with four zigzag chains (solid-black curve) and for six zigzag chains (short-dashed-red curve) and for eight zigzag chains (short-dotted-blue curve) in width.
