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…
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…
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…
Transport and localization of indirect excitons in a van der Waals heterostructure
L. H. Fowler-Gerace, Zhiwen Zhou, E. A. Szwed +2
Long lifetimes of spatially indirect excitons (IXs), also known as interlayer excitons, allow implementing both quantum exciton systems and long-range exciton transport. Van der Wa…
Long-range quantum transport of indirect excitons in van der Waals heterostructure
L. H. Fowler-Gerace, Zhiwen Zhou, E. A. Szwed +1
Long lifetimes of spatially indirect excitons (IXs), also known as interlayer excitons, make possible long-range IX propagation. Van der Waals heterostructures composed of atomical…
Voltage-controlled long-range propagation of indirect excitons in van der Waals heterostructure
L. H. Fowler-Gerace, D. J. Choksy, L. V. Butov
Indirect excitons (IXs), also known as interlayer excitons, can form the medium for excitonic devices whose operation is based on controlled propagation of excitons. A proof of pri…
Localized bright luminescence of indirect excitons and trions in MoSe/WSe van der Waals heterostructure
E. V. Calman, L. H. Fowler-Gerace, L. V. Butov +5
Indirect excitons (IX) in semiconductor heterostructures are bosons, which can cool below the temperature of quantum degeneracy and can be effectively controlled by voltage and lig…
