Excitonic pattern formation from a wrinkling instability in a van der Waals heterostructure
Zhiwen Zhou, L. H. Fowler-Gerace, W. J. Brunner +4
We studied photoluminescence of spatially indirect excitons (IXs) in a MoSe/WSe van der Waals heterostructure. We observed a quasi-periodic triangular pattern of IXs with a…
Efficient transport kinetics of indirect excitons in van der Waals heterostructure
Zhiwen Zhou, W. J. Brunner, E. A. Szwed +3
Exciton transport is fundamental for understanding transport phenomena in bosonic systems and for exploring excitation energy transfer in materials. Spatially indirect excitons (IX…
Transport of indirect excitons and exciton mediated spin transport in a van der Waals heterostructure in magnetic fields
Zhiwen Zhou, W. J. Brunner, E. A. Szwed +2
We studied transport of indirect excitons (IXs) and IX mediated spin transport in a MoSe/WSe van der Waals heterostructure in magnetic fields up to 8 T. We observed the lon…
Interference dislocations adjacent to emission spot
J. R. Leonard, L. H. Fowler-Gerace, Zhiwen Zhou +3
We studied interference dislocations (forks) adjacent to an emission spot in an interference pattern. The adjacent interference dislocations are observed in emission of excitons in…
Long-range spatial extension of exciton states in van der Waals heterostructure
Zhiwen Zhou, E. A. Szwed, W. J. Brunner +3
Narrow lines in photoluminescence (PL) spectra of excitons are characteristic of low-dimensional semiconductors. These lines correspond to the emission of exciton states in local m…
Mott transition in excitonic Bose polarons
E. A. Szwed, B. Vermilyea, D. J. Choksy +5
For a neutral system of positive and negative charges, such as atoms in a crystal, increasing the density causes the Mott transition from bound electrons to free electrons. The den…
