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…
Evidence of reduced surface electron-phonon scattering in the conduction band of Bi_{2}Se_{3} by non-equilibrium ARPES
A. Crepaldi, F. Cilento, B. Ressel +11
The nature of the Dirac quasiparticles in topological insulators calls for a direct investigation of the electron-phonon scattering at the \emph{surface}. By comparing time-resolve…
Combined large spin-splitting and one dimensional confinement in surface alloys
Alberto Crepaldi, Gustav Bihlmayer, Klaus Kern +1
We have found and characterized by angle-resolved photoelectron spectroscopy (ARPES) quasi-one dimensional spin-split states in chain-like surface alloys formed by large Z elements…
Direct view on the ultrafast carrier dynamics in graphene
Jens Christian Johannsen, Søren Ulstrup, Federico Cilento +11
The ultrafast dynamics of excited carriers in graphene is closely linked to the Dirac spectrum and plays a central role for many electronic and optoelectronic applications. Harvest…
Ultrafast photodoping and effective Fermi-Dirac distribution of the Dirac particles in Bi2Se3
A. Crepaldi, B. Ressel, F. Cilento +7
We exploit time- and angle- resolved photoemission spectroscopy to determine the evolution of the out-of-equilibrium electronic structure of the topological insulator Bi2Se. The re…
