Graphene made magnetic with hydrogen coating

Abstract:
Graphone, a new magnetic version of carbon monolayers called graphene, could enable a new breed of carbon spintronic devices, researchers claim.

Graphene, consisting of pure crystalline carbon sheets, cannot be doped with impurities to adjust its semiconducting and magnetic properties as easily as silicon since carbon does not readily "heal" implantations with annealing. Rather than implanting dopants, researchers say, a surface treatment can be used to adjust a carbon sheet's properties.

Researchers say hydrogen can be used to fine-tune graphene's metallic, semiconductor and magnetic properties, resulting in either graphene (metallic), graphane (semiconducting) or graphone (ferromagnetic).

"Dangling bonds of carbon carry a magnetic moment, and these can be aligned ferromagnetically," said professor Purusottam Jena of Virginia Commonwealth University in Richmond.
