Two-dimensional materials articles from across Nature Portfolio

Atomically thin single-crystalline high-κ dielectrics can be grown directly on a two-dimensional semiconductor by van der Waals epitaxy, providing ultrathin gate stacks with excellent interface quality.

There are theoretical predictions that topologically non-trivial states in materials leave tell-tale signs in the spatial structure of their wave functions. These have now been observed in monolayer materials.

Global topological invariants are a useful tool to understand electronic structure, but to understand emergent quantum phenomena, the local geometric structure of Bloch wavefunctions must be considered. In 2025, experiments have revealed the direct momentum-resolved measurement of the complete quantum metric tensor, enabling the experimental exploration of quantum geometry.

Two distinct types of atomic insulator can be distinguished by the distribution of charges within the unit cell. Now, real-space imaging of WSe₂ shows that it is a so-called obstructed insulator.

Nanoscale bandgap tuning in van der Waals heterobilayers using an electro-plasmonic nanocavity provides electrical control of exciton dynamics, producing localized interlayer exciton density gradients and enhanced diffusion currents in the nanoscale.

A self-powered platform integrates graphene-based ion-sensitive field-effect transistors, MoS₂ electronic circuits and silicon photovoltaics to digitize diverse liquid analytes under ambient light, enabling compact, autonomous, battery-free chemical analysis.

A computational ‘information co-evolution’ framework is developed for the discovery of covalent organic frameworks (COFs) for hydrogen peroxide photosynthesis. By integrating cross-level feature fusion with data augmentation and ensemble modelling, this strategy overcomes challenges in structural representation and data limitations, enabling the identification of high-performance COF candidates and the discovery of important structural motifs.

The MoSi₂N₄ family is an emerging class of van der Waals materials with interesting properties. Here, the authors report a systematic characterization of point defects in monolayer WSi₂N₄ and MoSi₂N₄, showing their influence on the electronic properties of the materials.

The scalable fabrication of high-performance p-type 2D transistors remains a major bottleneck towards the development of 2D electronics. Here, the authors report the wafer-scale synthesis of p-type 2H-MoTe₂ films with controllable thickness and the realization of medium scale integrated circuits, such as a 140-transistor full adder.

An article in Nature Physics reports how combining distinct transition metal dichalcogenide monolayers enables the formation of an emergent exciton crystal — the bosonic analogue of the fermionic Wigner crystal.

Covalent organic frameworks promise breakthroughs in water treatment, separations and photocatalysis. Yet their real-world performance is governed by sequence-dependent transformations — hydrolysis, photo-oxidation and defect-driven fragmentation — that can silently reshape pore chemistry and release mobile products. Transformation atlases built from laboratory and synchrotron and/or neutron characterization can now predict these trajectories and enable safer, more durable design.

Excitons are commonly regarded as massive composite quasiparticles. Now, experiments show that, in two-dimensional materials, light–matter interactions can turn excitons into massless collective modes with linear, photon-like dispersions.
