Phonon-assisted inter-valley scattering determines ultrafast exciton dynamics in MoSe bilayers
Sophia Helmrich, Kevin Sampson, Di Huang +10
While valleys (energy extrema) are present in all band structures of solids, their preeminent role in determining exciton resonances and dynamics in atomically thin transition meta…
High phonon-limited mobility of charged and neutral excitons in mono- and bilayer MoTe2
Sophia Helmrich, Alexander W. Achtstein, Hery Ahmad +5
We analyze the lineshape of the quasiparticle photoluminescence of monolayer and bilayer molybdenum ditelluride in temperature- and excitation intensity-dependent experiments. We c…
Biexciton fine structure in monolayer transition metal dichalcogenides
Alexander Steinhoff, Matthias Florian, Akshay Singh +8
The optical properties of atomically thin transition metal dichalcogenide (TMDC) semiconductors are shaped by the emergence of correlated many-body complexes due to strong Coulomb…
Long-Lived Valley Polarization of Intra-Valley Trions in Monolayer WSe2
Akshay Singh, Kha Tran, Mirco Kolarczik +9
We investigate valley dynamics associated with trions in monolayer tungsten diselenide (WSe2) using polarization resolved two-color pump-probe spectroscopy. When tuning the pump an…
