Graphene patterning is regarded as one of the areas of interest due to its necessity for applications. The current graphene micro-patterning techniques, such as EBL and NIL, are time consuming and scale with sample size. In such methods, graphene is patterned in a plasma environment through dry etching reactions with gases like O2. These reactions lead to rough edges formation and no crystal alignment in patterned graphene. Here, we present hot punching as a novel and feasible method for large-scale micro-patterning of CVD graphene sheets, after they are transferred to a PVA layer. With this method, we have been able to investigate some of mechanical behaviors of graphene such as tearing and cracking.
