Moiré-modulated valley in twisted bilayer and twisted double-bilayer MoTe
Wanying Chen, Hongyun Zhang, Jinxi Lu +18
Twisted MoTe hosts intriguing correlated quantum phenomena including the fractional quantum anomalous Hall effect in twisted bilayer (t-BL) MoTe near 3.7, which is…
Tunable electronic band structure in WSSe van der Waals Alloys
Meryem Bouaziz, Leonard Schue, Noeliarinala Felana Andriambelaza +12
The electronic structure of semiconducting 2D materials such as transition metal dichalcogenides (TMDs) is known to be tunable by its environment, from simple external fields appli…
Hybridization in van der Waals epitaxy of PtSe2/h-BN and PtSe2/graphene heterostructures
Meryem Bouaziz, Samir El Masaoudi, Aymen Mahmoudi +10
Van der Waals (vdW) heterostructures, which combine bi-dimensional materials of different properties, enable a range of quantum phenomena. Here, we present a comparative study betw…
Moiré enhanced flat band in rhombohedral graphene
Hongyun Zhang, Jinxi Lu, Kai Liu +17
The fractional quantum anomalous Hall effect (FQAHE) is a fascinating emergent quantum state characterized by fractionally charged excitations in the absence of magnetic field,whic…
Correlated topological flat bands in rhombohedral graphite
Hongyun Zhang, Qian Li, Michael G. Scheer +22
Flat bands and nontrivial topological physics are two important topics of condensed matter physics. With a unique stacking configuration analogous to the Su-Schrieffer-Heeger (SSH)…
