Electronic Structure of Epitaxial Single-Layer MoS
Jill A. Miwa, Søren Ulstrup, Signe G. Sørensen +5
The electronic structure of epitaxial single-layer MoS on Au(111) is investigated by angle-resolved photoemission spectroscopy. Pristine and potassium-doped layers are studied…
High Crystallinity and Decoupling of Graphene on a Metal: Reduced Coulomb Screening and Tunable pn-Junctions
Søren Ulstrup, Mie Andersen, Marco Bianchi +4
High quality epitaxial graphene films can be applied as templates for tailoring graphene-substrate interfaces that allow for precise control of the charge carrier behavior in graph…
Ultrafast Dynamics of Massive Dirac Fermions in Bilayer Graphene
Søren Ulstrup, Jens Christian Johannsen, Federico Cilento +14
Bilayer graphene is a highly promising material for electronic and optoelectronic applications since it is supporting massive Dirac fermions with a tuneable band gap. However, no c…
Extracting the Temperature of Hot Carriers in Time- and Angle-Resolved Photoemission
Søren Ulstrup, Jens Christian Johannsen, Marco Grioni +1
The interaction of light with a material's electronic system creates an out-of-equilibrium (non-thermal) distribution of optically excited electrons. Non-equilibrium dynamics relax…
