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 l…
