Manifestation of nonlocal electron-electron interaction in graphene
Søren Ulstrup, Malte Schüler, Marco Bianchi +5
Graphene is an ideal platform to study many-body effects due to its semimetallic character and the possibility to dope it over a wide range. Here we study the width of graphene's o…
Ultrafast Electron Dynamics in Epitaxial Graphene Investigated with Time- and Angle-Resolved Photoemission Spectroscopy
Søren Ulstrup, Jens Christian Johannsen, Alberto Crepaldi +11
In order to exploit the intriguing optical properties of graphene it is essential to gain a better understanding of the light-matter interaction in the material on ultrashort times…
Ramifications of Optical Pumping on the Interpretation of Time-Resolved Photoemission Experiments on Graphene
Søren Ulstrup, Jens Christian Johannsen, Federico Cilento +13
In pump-probe time and angle-resolved photoemission spectroscopy (TR-ARPES) experiments the presence of the pump pulse adds a new level of complexity to the photoemission process i…
Electron-phonon coupling in quasi free-standing graphene
Jens Christian Johannsen, Søren Ulstrup, Marco Bianchi +8
Quasi free-standing monolayer graphene can be produced by intercalating species like oxygen or hydrogen between epitaxial graphene and the substrate crystal. If the graphene is ind…
