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…

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…
