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…
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…
A self-consistent Hartree theory for lattice-relaxed magic-angle twisted bilayer graphene
Mohammed M. Al Ezzi, Liangtao Peng, Zhengyu Liu +4
For twisted bilayer graphene close to magic angle, we show that the effects of lattice relaxation and the Hartree interaction both become simultaneously important. Including both e…
Analytical Model for Atomic Relaxation in Twisted Moiré Materials
Mohammed M. Al Ezzi, Gayani N. Pallewela, Christophe De Beule +2
By virtue of being atomically thin, the electronic properties of heterostructures built from two-dimensional materials are strongly influenced by atomic relaxation. The atomic laye…
