"Electric-Field Control of Magnetism in Graphene Quantum Dots: Ab Initio Calculations." Physical Review B 82 (20): 201411.1098-01211550-235Xhttp://nrs.harvard.edu/urn-3:HUL.InstRepos:13479093Employing ab initio calculations we predict that the magnetic states of hydrogenated diamond-shaped zigzag graphene quantum dots (GQDs), each exhibiting unique electronic structure, can be selectively tuned with gate voltage, through Stark or hybridization electric-field modulation of the spatial distribution and energy of the spin-polarized molecular orbitals, leading to transitions between these states. Electrical read-out of the GQD magnetic state can be accomplished by exploiting the distinctive electrical properties of the various magnetic configurations.en-USJournal Article2014-12-0810.1103/PhysRevB.82.201411
