Dimensional variation of reconfigurable serpentine graphene nanoribbon under tension.

In this paper, we resort to single-layer graphene nanoribbon (GN) and atomistic simulation to explore the dimensional variation of serpentine graphene. A tensile model of serpentine GN is established, and its topology responses are investigated with some counterintuitive expectations. A laser scanning experiment on the serpentine sheet of paper is performed and compared, which can indirectly reflect the reduced-dimensionality tendency of serpentine GN in tension. As a result, serpentine GN provides a dynamic route of transforming lateral and longitudinal dimensions. Our obtained results can be used to the thermal, electric, or magnetic controlling in future applications. [ABSTRACT FROM AUTHOR]
