The first boron films that are just one atom thick have been produced by a team of researchers at several institutes in the US. A preliminary study of the ultrathin material called “borophene” suggests that it displays a variety of fascinating and potentially useful properties, including direction-dependent conductivity. However, unlike graphene – which comprises a single layer of carbon atoms – the boron films are not free-standing and are instead fixed to a metal substrate…..
