Description:
Author(s): Taisuke Ohta, Jeremy T. Robinson, Peter J. Feibelman, Aaron Bostwick, Eli Rotenberg, and Thomas E. Beechem We report a study of the valence band dispersion of twisted bilayer graphene using angle-resolved photoemission spectroscopy and ab initio calculations. We observe two noninteracting cones near the Dirac crossing energy and the emergence of van Hove singularities where the cones overlap for large tw... [Phys. Rev.
