Strong interlayer interactions in bilayer and trilayer moiré superlattices [PDF]

, 2022
Moiré superlattices constructed from transition metal dichalcogenides have demonstrated a series of emergent phenomena, including moiré excitons, flat bands, and correlated insulating states.

Moiré‐Assisted Realization of Octahedral MoTe2 Monolayer

Advanced Science, 2023
A current key challenge in 2D materials is the realization of emergent quantum phenomena in hetero structures via controlling the moiré potential created by the periodicity mismatch between adjacent layers, as highlighted by the discovery of ...

Chemically Reversible Translational Moiré Superlattice Formations in the 2D Films of Zinc-Phthalate Complex [PDF]

Two-dimensional (2D) moiré materials formed due to angular or translational mismatch between the consecutive lattices are emerging as extraordinary quantum materials, owing to their intrinsic physical properties that are different from ordinary 2D ...

Magic configurations in moiré superlattice of bilayer photonic crystals: Almost-perfect flatbands and unconventional localization

Physical Review Research, 2022
We investigate the physics of photonic band structures of the moiré patterns that emerged when overlapping two unidimensional photonic crystal slabs with mismatched periods. The band structure of our system is a result of the interplay between intralayer

Plasmons in graphene moiré superlattices [PDF]

, 2015
Moiré patterns are periodic superlattice structures that appear when two crystals with a minor lattice mismatch are superimposed. A prominent recent example is that of monolayer graphene placed on a crystal of hexagonal boron nitride.

Moiré‐Induced Symmetry Breaking of Charge Order in van der Waals Heterostructures

Advanced Materials, EarlyView.
A uniaxial moiré potential in misfit (MS)1+δTaS2 heterostructures selectively reshape charge order: the embedded 1H‐TaS2 layer hosts an incommensurate charge‐density wave, fragmented into nanometer domains and stripped of threefold symmetry. Superconductivity, however, remains uniform and fully gapped, revealing heterosymmetry stacking as a selective ...

Moiré Phase Mapping in Twisted Bilayer Liquid Crystals with Reconfigurable Light Polarization States

Advanced Materials, EarlyView.
Twisted bilayer liquid crystals are developed by vertical stacking assembly of two liquid crystals having designer domains and optical properties. These moiré‐symmetry, twisted liquid crystals demonstrate reconfigurable polarization states, moiré patterns and phases controlled by twist angles, providing a route to design active optical devices for ...

Spectrally Programmable Spin‐Polarized Photocurrents in WSe2–NiPS3 Magnetic van der Waals Heterostructures

Advanced Materials, EarlyView.
Heterostructure photodiode devices of p‐type WSe2 with n‐type NiPS3 constructs spectrally protected spin‐polarized photocurrents. The energy of the excitation photon serves as an independent control parameter for spin‐selective photocurrent generation. ABSTRACT Efficient generation and control of spin‐polarized currents in semiconductors remain central
