Only five non-metallic materials of the graphene family were known up to date: graphene, hBN, BCN, fluorographene, and graphene oxide. For the first time, crystalline thin films of triazine-based graphitic carbon nitride (TGCN) are now presented. TGCN is structurally similar to graphite but it is a semiconductor. The thin films are a few to several hundreds of atomic layers thick and display a direct bandgap between 1.6 and 2.0 eV.
