Microsecond Valley Lifetime of Defect-Bound Excitons in Monolayer WSe
Galan Moody, Kha Tran, Xiaobo Lu +6
In atomically thin two-dimensional semiconductors such as transition metal dichalcogenides (TMDs), controlling the density and type of defects promises to be an effective approach…
Moiré Excitons in Van der Waals Heterostructures
Kha Tran, Galan Moody, Fengcheng Wu +19
In van der Waals (vdW) heterostructures formed by stacking two monolayer semiconductors, lattice mismatch or rotational misalignment introduces an in-plane moiré superlattice. Whil…
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…
