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…
Role of electron-electron interactions in -valley twisted transition metal dichalcogenides
Christophe De Beule, Liangtao Peng, E. J. Mele +1
We investigate the role of long-range Coulomb interactions in -valley moirés using the self-consistent Hartree-Fock approximation. This platform was recently proposed [Nature 64…
Theory for Lattice Relaxation in Marginal Twist Moirés
Christophe De Beule, Gayani N. Pallewela, Mohammed M. Al Ezzi +3
Atomically thin moiré materials behave like elastic membranes where at very small twist angles, the van der Waals adhesion energy much exceeds the strain energy. In this ``marginal…
Coulomb screening of superconductivity in magic-angle twisted bilayer graphene
Julien Barrier, Liangtao Peng, Shuigang Xu +7
The origin of superconductivity in magic-angle twisted bilayer graphene has been a subject of intense debate. While some experimental evidence indicated an unconventional pairing m…
Imaging the Sub-Moiré Potential Landscape using an Atomic Single Electron Transistor
Dahlia R. Klein, Uri Zondiner, Amit Keren +10
Electrons in solids owe their properties to the periodic potential landscapes they experience. The advent of moiré lattices has revolutionized our ability to engineer such landscap…
