(a)–(b) Schematic diagrams of ring and crescent nano-structures on a gold coated glass substrate. The thickness of gold is 30 nm and the height of silver nano-structures is 75 nm. (c)–(d) Top view SEM images of graphene lies on ring and crescent nano-structures. Arrows point to the folds in the graphene on top of the crescent structure. Scale bars are 200 nm.
