Topological phase-diagram of time-periodically rippled zigzag graphene nanoribbons
The topological properties of electronic edge states in time-periodically driven spatially-periodic corrugated zigzag graphene nanoribbons are studied. An effective one-dimensionalHamiltonian is used to describe the electronic properties of graphene and the time-dependence is studiedwithin the Floquet formalism. Then the quasienergy spectrumof the evolution operator is obtained using analytical...

متن کاملEnhanced half-metallicity in edge-oxidized zigzag graphene nanoribbons.
We present a comprehensive theoretical study of the electronic properties and relative stabilities of edge-oxidized zigzag graphene nanoribbons. The oxidation schemes considered include hydroxyl, lactone, ketone, and ether groups. Using screened exchange density functional theory, we show that these oxidized ribbons are more stable than hydrogen-terminated nanoribbons except for the case of the...
