Abstract
Recently hybridized monolayers consisting of hexagonal boron nitride hBN phases inside a graphene layer have been synthesized and shown to be an effective way of opening band gap in graphene monolayers Ci et al in Nat Mater 95430–435 2010 In this paper we report a firstprinciples density functional theory study of the hBN domain size effect on the elastic properties of graphene/boron nitride hybrid monolayers hBNC We found that both inplane stiffness and longitudinal sound velocity of hBNC linearly decrease with hBN concentration Our results could be used for the design of future graphenebased nanodevices of surface acoustic wave sensors and waveguides
