Researchers at Japan Advanced Institute of Science and Technology (JAIST) have successfully fabricated suspended graphene nanomesh in a large area by helium ion beam microscopy. Six nm diameter nanopores were uniformly patterned on the 1.2 um long and 500 nm wide suspended graphene. By systematically controlling the pitch (nanopore's center to nanopore's center) from 15 nm to 50 nm, a series of stable graphene nanomesh devices were achieved. This provides a practical way to investigate the intrinsic properties of graphene nanomesh towards applications for gas sensing, phonon engineering, and quantum technology.
