Phonon-pump extreme-ultraviolet-photoemission probe in graphene: Anomalous heating of dirac carriers by lattice deformation
Richard Chapman, Emma Springate, Stefan Link, Ulrich Starke, Burkhard Sachs, Martin Eckstein, Tim O. Wehling , Mikhail I. Katsnelson, Alexander Lichtenstein and Andrea Cavalleri. Journal: Physical Review [...] graphene by driving its lattice at resonance with the in-plane E-1u lattice vibration at 6.3 mu m. Using time-and angle-resolved photoemission spectroscopy (tr-ARPES) with extreme-ultraviolet (XUV) pulses, we
