The growth of monolayer hexagonal boron nitride (hBN) on insulating substrates could promote high-end applications of 2D (opto-)electronic devices, but remains difficult to achieve. Here, the authors report a stamp-like growth-transfer technique to produce inch-sized single-crystal hBN and graphene monolayers on various insulating substrates.
