摘要：

Hexagonal boron nitride monolayers with domain sizes up to 700 μm2 and geometry from triangle to hexagon are fabricated through a refined control over the precursor and morphology of the copper substrate. Hydrogen etching is shown to tailor the h-BN monolayers precisely along the grain boundaries, providing their morphology over micrometer scale and a new avenue toward fabricating nanoribbons. © 2015 WILEY-VCH Verlag GmbH & Co.
