Quantum effects in graphitic materials: Colossal magnetoresistance, Andreev reflections, ferromagnetism, and granular superconductivity
N Gheorghiu,C. Ebbing,BT Pierce,Timothy J. Haugan +3 more
- 01 Mar 2020
TL;DR: In this article, the Andreev reflection and the interband Klein tunneling couple electronlike and hole-like states through the action of either a superconducting pair potential or an electrostatic potential.

Electric-Field Induced Strange Metal States and Possible High-Temperature Superconductivity in Hydrogenated Graphitic Fibers
TL;DR: In this article, the effects from increasing the strength of the applied electric field on the charge transport of hydrogenated graphitic fibers were studied and the temperature-dependent resistivity shows linear, step-like transitions from insulating to metallic states.

Superconductivity in Hydrogenated Graphites
TL;DR: In this paper, transport and magnetization measurements on graphitic materials that have been hydrogenated after being treated with octane were reported. And they found that either a magnetic or an electric field can drive this hydrogenated graphitic system to superconducting state below 50 K.
