Strain‐Field‐Induced Bandgap Opening in Bilayer Graphene

Small, EarlyView.
Bandgaps of up to 50 meV are opened in bilayer graphene through periodic in‐plane strain fields imposed by a three‐layer graphene/organic 2D crystal/graphene heterostructure. The bandgap originates not from bilayer formation itself, but from bond‐length modulation at domain boundaries.

Magic of high-order van Hove singularity

Nature Communications, 2019
Correlation effect is essential to stabilize exotic phases such as superconductivity in twisted bilayer graphene. Here, Yuan et al. predict significantly enhanced electron correlation effects due to an emergent high-order van Hove singularity in a two ...

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.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

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 ...
