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…

Tuning intraband and interband transition rates via excitonic correlation in low-dimensional semiconductors
Josep Planelles, Alexander W. Achtstein, Riccardo Scott +2
We show that electron-hole correlation can be used to tune interband and intraband optical transition rates in semiconductor nanostructures with at least one weakly confined direct…

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…
