[资源] 最新:Geim又一篇science 石墨烯光谱

The nematic phase transition in electronic liquids, driven by Coulomb interactions, represents
a new class of strongly correlated electronic ground states. We studied suspended samples of bilayer
graphene, annealed so that it achieves very high quasiparticle mobilities (greater than 106 square
centimers per volt-second). Bilayer graphene is a truly two-dimensional material with complex chiral
electronic spectra, and the high quality of our samples allowed us to observe strong spectrum
reconstructions and electron topological transitions that can be attributed to a nematic phase transition
and a decrease in rotational symmetry. These results are especially surprising because no interaction
effects have been observed so far in bilayer graphene in the absence of an applied magnetic field.[ Last edited by taozhikai on 2011-8-12 at 21:36 ]
