Evidence of a gate-tunable Mott insulator in a trilayer graphene moiré superlattice [PDF]

, 2019
The Mott insulator is a central concept in strongly correlated physics and manifests when the repulsive Coulomb interaction between electrons dominates over their kinetic energy1,2.

Duality between atomic configurations and Bloch states in twistronic materials

Physical Review Research, 2020
The relative orientation (twist) of successive layers of stacked two-dimensional (2D) materials creates variations in the interlayer atomic registry. The variations often form a superlattice, called a moiré pattern, which can alter electronic properties.

Tailoring Symmetry Breaking in Engineered van der Waals Superlattices

Advanced Materials, Volume 38, Issue 57, 13 October 2026.
We pioneer a scheme to tailor superpotentials in graphene based on intrinsic substrate electronic orders rather than twist angle. The resulting superpotential folds graphene's Dirac cones to either Γ$\Gamma$ or K‐points, leading to distinct symmetry behaviors.

Advance in twisted transition metal dichalcogenides: synthesis, characterization, and properties

JPhys Materials
The twist angle regulation strategy provides a feasible tool for studying the emerging properties of transition metal dichalcogenides (TMDCs). For the twisted TMDCs (t-TMDCs), there is the lattice mismatch and twist between layers, thus forming moiré ...

Ultrathin Freestanding BiFeO3 Membranes Grown by Pulsed Laser Deposition

Small, Volume 22, Issue 56, 8 October 2026.
Ultrathin freestanding BiFeO3 membranes down to five‐unit cells are realized by pulsed laser deposition using a water‐soluble Sr3Al2O6 sacrificial layer. Strontium diffusion is revealed to drive the spontaneous formation of an Aurivillius‐like phase, while ultrathin SrRuO3 interlayers suppress interfacial intermixing, preserve polar tetragonality, and ...

Straintronics and Twistronics in 2D Materials: Structural Control and Predictive Design

Small, Volume 22, Issue 56, 8 October 2026.
Strain and twist engineering in 2D materials is established as a programmable design parameter responsible for reconstructing lattices, tuning interlayer coupling, and developing new quantum functionalities. Through the integration of advanced fabrication techniques, multiscale characterization, computational modeling, and machine learning, this review

Twister: Construction and structural relaxation of commensurate moiré superlattices

, 2022
Introduction of a twist between layers of two-dimensional materials which leads to the formation of a moiré pattern is an emerging pathway to tune the electronic, vibrational and optical properties.

Bichromatic moiré superlattices for tunable quadrupolar trions and correlated states

Nature Communications
Moiré superlattices in transition metal dichalcogenide heterostructures provide a platform to engineer many-body interactions. Here, we realize a bichromatic moiré superlattice in an asymmetric WSe2/WS2/WSe2 heterotrilayer by combining R- and H-stacked ...

Difference frequency generation by quasi-phase matching in periodically intermixed semiconductor superlattice waveguides [PDF]

, 2011
Wavelength conversion by difference frequency generation is demonstrated in domain-disordered quasi-phase-matched waveguides. The waveguide structure consisted of a GaAs/AlGaAs superlattice core that was periodically intermixed by ion implantation.
