Anomalous Pressure-Enhanced Polarization in Sliding Ferroelectrics
Lujin Min, Sahas Kamat, Ameer Mustafa +8
Hydrostatic pressure commonly suppresses polarization in conventional displacive ferroelectrics by weakening the off-center ionic distortion. Sliding ferroelectrics may provide a c…
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 elastic…
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 prop…
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…
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…
Polarization textures in crystal supercells with topological bands
Wojciech J. Jankowski, Daniel Bennett, Aneesh Agarwal +2
Two-dimensional materials are a highly tunable platform for studying the momentum space topology of the electronic wavefunctions and real space topology in terms of skyrmions, mero…
Photo-induced electronic and spin topological phase transitions in monolayer bismuth
Bo Peng, Gunnar F. Lange, Daniel Bennett +3
Ultrathin bismuth exhibits rich physics including strong spin-orbit coupling, ferroelectricity, nontrivial topology, and light-induced structural dynamics. We use \textit{ab initio…
