New ‘brick’ for nanotechnology: Graphene Nanomesh

Researchers at Japan advanced institute of science and technology (JAIST) successfully fabricated suspended graphene nanomesh (GNM) by using the focused helium ion beam technology. The 2D array of 6nm diameter nanopores were patterned on a large-area suspended graphene uniformly. By systematically controlling the pitch from 15 nm to 50 nm, a series of stable GNM devices were achieved. This technology provides a new approach to explore nanoscale thermal engineering, advanced sensing, and quantum technology.
