Spin and Valley Control of Free Carriers in Single-Layer WS
Søren Ulstrup, Antonija Grubišić Čabo, Deepnarayan Biswas +11
The semiconducting single-layer transition metal dichalcogenides have been identified as ideal materials for accessing and manipulating spin- and valley-quantum numbers due to a se…
Generation and evolution of spin-, valley- and layer-polarized excited carriers in inversion-symmetric WSe2
Roman Bertoni, Christopher W. Nicholson, Lutz Waldecker +11
Manipulation of spin and valley degrees of freedom is a key step towards realizing novel quantum technologies, for which atomically thin transition metal dichalcogenides (TMDCs) ha…
Phonon-pump XUV-photoemission-probe in graphene: evidence for non-adiabatic heating of Dirac carriers by lattice deformation
Isabella Gierz, Matteo Mitrano, Hubertus Bromberger +11
We modulate the atomic structure of bilayer graphene by driving its lattice at resonance with the in-plane E1u lattice vibration at 6.3um. Using time- and angle-resolved photoemiss…
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…
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…
