WebMar 23, 2016 · Abstract In this Letter, we report the observation of thermally induced rotation of graphene on hexagonal boron nitride ( h -BN). After the rotation, two thermally stable configurations of graphene on h -BN with a relative lattice twisting angle of 0° (most stable) and 30° (metastable), respectively, were found. http://jarilloherrero.mit.edu/research/graphene-boron-nitride-heterostructures/
