The hexagonal boron nitride nanomesh is an inorganic two-dimensional material, similar to graphene. It was discovered in 2003 at the University of Zurich, Switzerland [Corso et al., Science 303, 217 (2004)]

Three-dimensional view of the nanomesh [h-BN/Rh(111)] with one trapped Cu-phthalocyanine molecule (C₃₂H₁₆CuN₈) at room temperature.

The mesh is synthetised at 1000 K and stable in air and liquids.

It consists of a single layer of boron nitride, has a corrugation of about 0.1 nm and a superlattice constant of 3.2 nm. Picture from the article e-Journal of Surface Science and Nanotechnology 303, 62-64 (2010)
