π-Plasmon Dispersion in Free-Standing Monolayer Graphene Investigated by Momentum-Resolved Electron Energy-Loss Spectroscopy
Graphene is a single layer of carbon atoms densely packed in a honeycomb lattice with each carbon atom accommodating four valence electrons: one π electron and three σ electrons [1]. The lone unpaired π electron in the half-filled pz orbital would form a π bond with the neighboring carbon atoms leading to delocalized π bands. Three σ electrons, sp 2 -hybridized with neighboring three carbon ato...
متن کاملObservation of plasmarons in quasi-freestanding doped graphene.
A hallmark of graphene is its unusual conical band structure that leads to a zero-energy band gap at a single Dirac crossing point. By measuring the spectral function of charge carriers in quasi-freestanding graphene with angle-resolved photoemission spectroscopy, we showed that at finite doping, this well-known linear Dirac spectrum does not provide a full description of the charge-carrying ex...
متن کاملSevere constraints on Loop-Quantum-Gravity energy-momentum dispersion relation from black-hole area-entropy law
We explore a possible connection between two aspects of Loop Quantum Gravity which have been extensively studied in the recent literature: the black-hole area-entropy law and the energymomentum dispersion relation. We observe that the original Bekenstein argument for the areaentropy law implicitly requires information on the energy-momentum dispersion relation. Recent results show that in first...
متن کاملConstraining the energy-momentum dispersion relation with Planck-scale sensitivity using cold atoms.
We use the results of ultraprecise cold-atom-recoil experiments to constrain the form of the energy-momentum dispersion relation, a structure that is expected to be modified in several quantum-gravity approaches. Our strategy of analysis applies to the nonrelativistic (small speeds) limit of the dispersion relation, and is therefore complementary to an analogous ongoing effort of investigation ...
متن کاملLenosky’s energy and the phonon dispersion of graphene
We calculate the phonon spectrum for a graphene sheet resulting from the model proposed by Lenosky et al. Nature London 355, 333 1992 for the free energy of the lattice. This model takes into account not only the usual bond-bending and stretching terms, but it also captures the possible misalignment of the pz orbitals. We compare our results with previous models used in the literature and with ...
