Welcome to the Nature Communications Editors’ Highlights webpage on condensed-matter physics. Each month our editors select a small number of Articles recently published in Nature Communications that they believe are particularly interesting or important.

The aim is to provide a snapshot of some of the most exciting work published in the area of condensed-matter physics at Nature Communications.

Make sure to check the Editors' Highlights page each month for new featured articles.

Here, the authors develop a spectroscopic technique whereby individual defects in an ultrathin hBN dielectric, placed in proximity to graphene, act as quantum dots. Dot-assisted tunneling is highly sensitive to the nearby graphene excitation spectrum, and allows probing of energy splitting in the excited Landau levels.

The ultrafast carrier dynamics across the van der Waals interface of transition metal dichalcogenide heterostructures govern the formation and funnelling of excitons. Here, the authors demonstrate a reversible switch from exciton dissociation to exciton funnelling in a MoSe2/WS2 heterostructure, which manifests itself as a photoluminescence quenching-to-enhancement transition.

The authors investigate the interplay between the stacking order and the interlayer coupling in MoS2 homobilayers as well as artificially stacked bilayers grown by chemical vapour deposition, and identify the interlayer exciton absorption and A-B exciton separation as indicators for interlayer coupling.

Long carrier lifetimes are beneficial for graphene-based optoelectronics, but carrier recombination processes in graphene possess sub-picosecond characteristic times. Here, the authors report carrier lifetimes ~30 ps at low energy in graphene/hBN Zener-Klein transistors, attributed to interband Auger processes.

Precisely strained graphene layers can enable observation of periodic pseudo-magnetic fields with high symmetry. Here, the authors report experimental tuning of large area periodic pseudo-magnetic fields within twisted bilayer graphene and massive Dirac electrons having circularly localized pseudo-Landau levels.

A plethora of solid-state nanodevices rely on engineering the quantization of electrons in quantum wells. Here, the authors leverage the thickness of exfoliated 2D crystals to control the quantum well dimensions in few-layer semiconductor InSe and investigate the resonance features in the tunnelling current, photoabsorption and light emission spectra.

Dielectric nano-antennas may be used as a platform for boosting light-matter coupling in 2D semiconductors. Here, the authors demonstrate the coupling of atomically thin WSe $${}_{2}$$ 2 with low-loss, high-refractive-index GaP nano-antennas and observe a 10000-fold WSe $${}_{2}$$ 2 photoluminescence enhancement.
