WebBEC-BCS crossover of exciton condensation in graphene double-layer. In an electronic double-layer system under strong magnetic fields, electron-like and hole-like carriers of different layers can bind by Coulomb interaction to form excitons, which condense into superfluid phases at low temperatures. When the densities of the excitons are low ... Web14. máj 2009 · The Raman spectral signature of folded graphene layers for one to six layers was studied. Folding allows realization of rotational disorder in otherwise perfect samples. We show that the two-dimensional Raman band of the folded sample is up shifted compared to the unfolded sample.
