ABSTRACT
Here, we report a facile method to fabricate a graphene nanomesh (GNM) by using a platinum (Pt) metal nano-network as a pattern mask. A hexagonally ordered Pt nano-network (i.e. nanomesh) with high-density arrays of periodic nano-holes was synthesized using an anodized alumina template, which served perfectly as a pattern mask for generating GNMs with tunable pore neck widths. Altering the neck width of the pores allows the modulation of the electrical conductivity of the GNMs. Resultant GNMs were further characterized using Raman spectroscopy and their electrical properties as conducting channels in field-effect transistors (FETs) were evaluated as a function of neck width. This synthetic route for producing GNMs provides a low-cost and simple way to fabricate GNMs for use in future fundamental studies related to graphene.
