Abstract Scope |
Surface corrugations (i.e., ripples and wrinkles) in atomically-thin two-dimensional (2D) materials are often considered to be undesirable imperfections. However, new light has recently been shed on the potential of wrinkles since it is found that these wrinkles can impose positive changes on the 2D materials. Diverse approaches have thus been applied to intentionally produce and manipulate wrinkles, but it remains a challenge to precisely control the position, orientation, and shape of the individual wrinkles. In this study, we propose a novel wallpapering-inspired strategy to create wrinkles in a desired location and direction of single-layer graphene. This approach enables to produce well-controlled graphene wrinkles (e.g., microscale lattice patterns of graphene wrinkles with nanometer-scale width and height). The detailed wrinkling process and corresponding mechanism were characterized by correlating the size and shape of graphene wrinkles with their mechanical behaviors. |
