High-mobility spin transport mediated by indirect excitons in a van der Waals heterostructure
Zhiwen Zhou, W. J. Brunner, Luc M. Nguyen +4
Efficient spin transport with high spin mobility is of both fundamental and practical significance for spintronics. Spin can be transferred by moving particles. However, particle s…
Transport kinetics in excitonic Mott insulator
W. J. Brunner, Zhiwen Zhou, Luc M. Nguyen +4
Indirect excitons (IXs) in a periodic moiré potential in a van der Waals heterostructure form an experimental platform for exploring Bose-Hubbard physics, including the superfluid…
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…
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…
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…
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…
Excitonic Bose-polarons in electron-hole bilayers
E. A. Szwed, B. Vermilyea, D. J. Choksy +6
Bose polarons are mobile impurities dressed by density fluctuations of a surrounding degenerate Bose gas. These many-body objects have been realized in ultracold atomic gasses and…
Long-distance decay-less spin transport in indirect excitons in a van der Waals heterostructure
Zhiwen Zhou, E. A. Szwed, D. J. Choksy +2
In addition to its fundamental interest, the long-distance spin transport with suppressed spin losses is essential for spintronic devices. However, the spin relaxation caused by sc…
