WSe2/WS2moiré superlattices by combining optical anisotropy and electronic compressibility measurements. We find strong electronic anisotropy over a large doping range peaked at 1/2 filling of the moiré superlattice. The 1/2 state is incompressible and assigned to an insulating stripe crystal phase....
We investigate the diffusion of photoexcited electron–hole pairs, or excitons, at the interface of WS2/WSe2 van der Waals heterostructure over a wide range of temperatures. We observe the appearance of distinct interlayer excitons for parallel and antiparallel stacking and track their diffusion ...
WSe2/WS2 vertically stacked bilayer heterostructures with controllable commensurate crystallographic alignments(so called AA and AB stacki ng),by controlling the deposition temperature.Moire patter ns were obtai ned in bothAA and AB stacked WSe2/WS2 heterostructures.The stacking configuration of the ...
In addition to their pronounced effects on single-particle states, moire superlattices have recently been predicted to host excited states such as moire exciton bands(13-15). Here we report the observation of moire superlattice exciton states in tungsten diselenide/tungsten disulfide (WSe2/WS2) ...
These moiré exciton states manifest as multiple emergent peaks around the original WSe2 A exciton resonance in the absorption spectra, and they exhibit gate dependences that are distinct from that of the A exciton in WSe2 monolayers and in WSe2/WS2 heterostructures with large twist angles. These...
Here we investigated interlayer exciton dynamics and transport in WS–WSeheterobilayers in time, space and momentum domains using transient absorption microscopy combined with first-principles calculations. We found that the exciton motion is modulated by twist-angle-dependent moiré potentials around 100...

When a vertically stacked heterobilayer comprising of a WSe2 monolayer on a WS2 monolayer is first fabricated, the heterobilayer behaves like two independent monolayers because of the presence of a large interlayer separation. However, after the stacked heterobilayer is subjected to a focused laser ...
Remarkably Deep Moire Potential for Intralayer Excitons in MoSe2/MoS2 Twisted Heterobilayers However, quantifying the moire potential for excitons is nontrivial. By creating a large ensemble of MoSe2/MoS2 heterobilayers with a systematic variation ... BH Lin,YC Chao,H Ita,... - 《Nano Letters》...
