Emergence of π-magnetism in open-shell nanographenes has been theoretically predicted
decades ago but their experimental characterization was elusive due to the strong chemical …

The electronic properties of graphene, a two-dimensional crystal of carbon atoms, are
exceptionally novel. For instance, the low-energy quasiparticles in graphene behave as …

Low-dimensional materials are of great interest to both theorists and experimentalists, owing
to their novel electronic properties which arise mainly because of a host of quantum …

We perform first-principles calculations based on density functional theory to study quasi-
one-dimensional edge-passivated (with hydrogen) zigzag graphene nanoribbons of various …

Investigations of the magnetic properties of graphenes prepared by different methods reveal
that dominant ferromagnetic interactions coexist along with antiferromagnetic interactions in …

Graphenes with varying number of layers can be synthesized by using different strategies.
Thus, single-layer graphene is prepared by micromechanical cleavage, reduction of single …

High-temperature ferromagnetism in graphene and other graphite-derived materials
reported by several workers has attracted considerable interest. Magnetism in graphene and …

Charge-transfer between electron–donor and–acceptor molecules is a widely studied
subject of great chemical interest. Some of the charge-transfer compounds in solid state …

The influence of carrier density on magnetism in a zigzag graphene nanoribbon is studied in
a π-orbital Hubbard-model mean-field approximation. Departures from half filling alter the …

Atomistic simulations are performed to study the nonlinear mechanical behavior of graphene
