The electronic properties of graphene can be significantly altered by placing it on top of hexagonal boron nitride (another 2D material that has the same type of honeycombed structure as graphene) thanks to the emergence of new “Dirac points” at an energy determined by the rotational angle between the two materials. This result, from researchers in the UK and Germany, could help in the design of novel optical and optoelectronic devices with tuneable properties……….
