Hidden valley dynamics behind vanishing circular polarization in moiré excitons
Yuto Urano, Lata Chouhan, Nurul Fariha Ahmad +4
Optically addressable valley degrees of freedom in transition-metal dichalcogenide heterostructures provide a powerful platform for valleytronic and quantum-optical functionalities…
Hierarchical spectral inhomogeneity in photoluminescence of a twisted MoSe2/WSe2 heterobilayer moiré superlattice revealed by hyperspectral mapping
Nurul Fariha Ahmad, Yuto Urano, Kenji Watanabe +3
Low-temperature photoluminescence from MoSe2/WSe2 moire superlattice often consists of a broad interlayer emission background with dense, narrow peaks, making microscopic line-by-l…
Strain Correlated Linearly Polarized Photoluminescence in WS2/WSe2 Moiré Superlattices
Yuto Urano, Ryo Tamura, Yui Tamogami +6
Reliable optical control of valley degrees of freedom in moiré excitons requires that the emitted polarization faithfully reflect the underlying valley state. Here, we show that li…
Assessment of valley coherence in a high-quality monolayer molybdenum diselenide
Yuto Urano, Xue Mengsong, Kenji Watanabe +2
We investigate the valley coherence in high and low-quality monolayer MoSe2 by polarization-resolved photoluminescence spectroscopy. The observed valley coherence is on the order o…
