▎ 摘　　要

NOVELTY - Doped, at least partially saturated graphene is claimed, where the saturation is by hydrogen or halogen, or by hydrogen and halogen. USE - The graphene is useful in electronic devices including transistors, and as conductors including microcircuits or bulk conductors. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) at least partially saturated graphene at a temperature below its superconducting critical temperature; (2) a doped diamond nano-rod at a temperature below its superconducting critical temperature; (3) a device-I comprising a layer of at least partially saturated graphene, where the saturation is by hydrogen and/or halogen, and a gate layer on it; (4) a device-II comprising a diamond nano-rod, and a gate layer on it; and (5) a substance having a carbon structure in which carbon atoms are bonded together by sp3 bonds, and the carbon structure is low dimensional, exhibiting superconductivity.
