The influence of electron-electron scattering on quasiparticle lifetimes in\ngraphite is calculated. In the limit when the Fermi surface is reduced to\nisolated points in the Brillouin Zone, the suppression of screening leads to\nnon Fermi liquid behavior. The inverse lifetime increases linearly with energy,\nin agreement with recent experiments. Similar features should also be present\nin narrow gap semiconductors, and in carbon nanotubes.\n
A calculation of the electron quasiparticle lifetime in a disordered metal due to electron-electron scattering is given. The calculation takes account of the diffusive nature of...
We have produced ultrathin epitaxial graphite films which show remarkable 2D\nelectron gas (2DEG) behavior. The films, composed of typically 3 graphene\nsheets, were grown by th...
Raman spectroscopy has historically played an important role in the structural characterization of graphitic materials, in particular providing valuable information about defect...
