Researchers of the Institute of Physics of the CAS and University of Vienna work together on novel graphene-diamond heterojunctions within the project supported by the Czech Science Foundation (GACR) and Austrian Science Fund (FWF). While the energy bandgap of 5.5 eV in the diamond electronic structure leads to the electrical resistivity as high as 1018 Ωm, graphene shows a zero bandgap at Fermi level behaving as a semimetal with extraordinary electronic...
