Magnetic and nematic order of Bose-Fermi mixtures in moiré superlattices of 2D semiconductors
Feng-Ren Fan, Tixuan Tan, Chengxin Xiao +1
We investigate the magnetic orders in a mixture of Boson (exciton) and Fermion (electron or hole) trapped in transition-metal dichalcogenides moiré superlattices. A sizable antifer…
Experimental signature of layer skyrmions and implications for band topology in twisted WSe2 bilayers
Fan Zhang, Nicolás Morales-Durán, Yanxing Li +13
Transition metal dichalcogenide (TMD) twisted homobilayers have been established as an ideal platform for studying strong correlation phenomena, as exemplified by the recent discov…
An active metasurface enhanced with moiré ferroelectricity
Dong Seob Kim, Chengxin Xiao, Roy C. Dominguez +11
Semiconductor moiré systems, characterized by their periodic spatial light emission, unveil a new paradigm of active metasurfaces. Here, we show that ferroelectric moiré domains fo…
Emergence of moiré superlattice potential in graphene by twisted-hBN layers
Tianyu Zhang, Chengxin Xiao, Hongxia Xue +2
Moiré superlattices formed in stacks of two or more 2D crystals with similar lattice structures have recently become excellent platforms to reveal new physics in low-dimensional sy…
