## Description

- description: We report the use of a novel atomic carbon source for the MBE of graphene
    layers on hBN flakes and on sapphire wafers at substrate growth temperatures between
    1400 and 1500C. The source produces a flux of predominantly atomic carbon, which
    diffuses through the walls of a Joule-heated tantalum tube filled with graphite
    powder. We demonstrate deposition of carbon on sapphire with carbon deposition
    rates up to 12 nm/h. AFM measurements reveal the formation of hexagonal moire
    patterns when graphene monolayers are grown on hBN flakes under optimum conditions.
    At MBE growth temperatures we observe etching of the sapphire wafer surface by
    the flux from the atomic carbon source, which we have not observed in the MBE
    growth of graphene with the sublimation carbon source.
