Twist-driven wide freedom of indirect interlayer exciton emission in MoS2/WS2 heterobilayers
Cell Reports Physical Science, 2021 Summary: Theoretical and first-principal studies involving twisted two-dimensional (2D) heterobilayer transition metal dichalcogenides (TMDs) predict interlayer exciton (ILE) emission energy amplitudes (the energy difference between the lowest and the ...

Enhanced colloidal transport in twisted magnetic patterns
Communications Physics, 2022 Bilayers of two-dimensional materials twisted at specific angles can exhibit exceptional properties such as the occurrence of unconventional superconductivity in twisted graphene. We demonstrate here that novel phenomena in twisted materials emerges also

Quantum Phase Transitions in Graphene Coupled to a Twisted WSe<sub>2</sub> Moiré Ferroelectricity. [PDF]
Adv MaterMoiré ferroelectricity in twisted WSe2 (t‐WSe2) breaks graphene's sublattice symmetry, inducing a room‐temperature metal‐insulator transition. Coupling graphene with ferroelectric domains of t‐WSe2 creates local Dirac points and metallic phases with Fermi‐liquid and non‐Fermi‐liquid behavior.

Out-of-Plane Dielectric Susceptibility of Graphene in Twistronic and Bernal Bilayers [PDF]
Nano Letters, 2021 We describe how the out-of-plane dielectric polarizability of monolayer graphene influences the electrostatics of bilayer graphene -- both Bernal (BLG) and twisted (tBLG). We compare the polarizability value computed using density functional theory with the output from previously published experimental data on the electrostatically controlled ...

Twistronics of Kekulé Graphene: Honeycomb and Kagome Flat Bands
Physical Review Letters, 2023 Kekulé-O order in graphene, which has recently been realized experimentally, induces Dirac electron masses on the order of $m \sim 100 \text{meV}$. We show that twisted bilayer graphene in which one or both layers have Kekulé-O order exhibits nontrivial flat electronic bands on honeycomb and kagome lattices.

Electronic Raman Scattering in Twistronic Few-Layer Graphene [PDF]
Physical Review Letters, 2020 We study electronic contribution to the Raman scattering signals of two-, three- and four-layer graphene with layers at one of the interfaces twisted by a small angle with respect to each other. We find that the Raman spectra of these systems feature two peaks produced by van Hove singularities in moiré minibands of twistronic graphene, one related to ...

Chiral-magic angle of nanoimprint meta-device
Nanophotonics, 2023 The magic angle of Twistronics has attracted a lot of attention because of its peculiar electrical characteristics. Moiré patterns formed by the superlattice of a twisted bilayer change overall physical properties.

Heterostrain and temperature-tuned twist between graphene/h-BN bilayers
Scientific Reports, 2023 Two-dimensional materials stacked atomically at small twist angles enable the modification of electronic states, motivating twistronics. Here, we demonstrate that heterostrain can rotate the graphene flake on monolayer h-BN within a few degrees (− 4° to ...
