More on: Unexpected graphene behaviour no comment steve bush 30th April 2014 Get news by email Researchers at the University of Manchester found a mechanism that could explain unusual electronic and optical behaviour in graphene , and another route to give it a bandgap. The work involved spreading mono-layer flakes of graphene on a thin (20nm) layer of boron nitride (BN). Both materials have a hexagonal two-dimensional structure – there is increasing interest in the interaction of various 2-d materials, phosphorene and molybdenum di-sulphide are others. LINK Some language is required here: when two layers of graphene are aligned with one another exactly, atoms from the layers attract each other and lock the alignment, and they are said to be ‘commensurate’. Boron nitride’s lattice constant is 1.8% larger than graphene. “There has been work done to see if graphene and boron...
