Lattice Relaxation in Moiré Heterobilayers
Christophe De Beule, Yiyang Lai, Liangtao Peng +2
We develop an analytical theory for lattice relaxation in twisted moiré heterobilayers, accounting for lattice mismatch, twist, external biaxial heterostrain, and different elasti…
Imaging topological polar structures in marginally twisted 2D semiconductors
Thi-Hai-Yen Vu, Daniel Bennett, Gayani Nadeera Pallewella +16
Moire superlattices formed in van der Waals heterostructures due to twisting, lattice mismatch and strain present an opportunity for creating novel metamaterials with unique proper…
Disorder-induced symmetry breaking in moiré bands of marginally twisted bilayer MoS
Pablo Reséndiz-Vázquez, Christophe de Beule, Thi-Hai-Yen Vu +8
Twisted transition-metal dichalcogenides host highly tunable moiré potentials, flat bands, and correlated electronic phases, yet the role of disorder in shaping these emergent pro…
Shift photocurrent vortices from topological polarization textures
Aneesh Agarwal, Wojciech J. Jankowski, Daniel Bennett +1
Following the recent interest in van der Waals (vdW) ferroelectrics, topologically nontrivial polar structures have been predicted to form in twisted bilayers. However, these struc…
