Repeated growth and transfer of h-BN films using Ni(111) single-crystal substrate. (a) Schematic illustration of the experiment. (b) h-BN films transferred onto SiO2/Si substrates. (c) Optical microscope images of h-BN films on SiO2/Si substrates obtained from the same Ni(111) substrate with different numbers of uses. APCVD, atmospheric pressure chemical vapor deposition; h-BN, hexagonal boron nitride.
