Rotational symmetry is shown to protect the quadratic dispersion of out-of-plane flexural vibrations in graphene and other two-dimensional materials against phonon–phonon interactions, making the bending rigidity of these materials non-divergent. The quadratic dispersion is then consistent with the propagation of sound in the graphene plane.

Silicon-integrated graphene photodetectors exhibit promising bandwidths at telecom wavelengths, but their responsivity is usually limited. Here, the authors report the wafer-scale fabrication of waveguide-integrated detectors based on twisted bilayer graphene, showing responsivities up to 0.65 A/W and 3-dB bandwidths >65 GHz.

Interacting electrons can collectively act as a viscous flow resembling a classical fluid, a phenomenon termed electron hydrodynamics. Here, the authors develop a framework to describe electron flow in narrow channels, demonstrating that the requirements for achieving electron hydrodynamic transport can be extended beyond what is currently considered possible.

Graphene oxide is a promising material for molecular separation technologies. Here, the authors propose a realistic staggered stacking structure that plays a crucial role in H/D recognition in water adsorption, as well as high mobilities of water.

Moiré materials are a versatile and tunable platform that offers a wide variety of lattice constants, energy scales and symmetries, leading to a rich interplay of electron correlations and topology. This Review summarizes recent breakthroughs in topological and Berry physics in moiré materials.

By transferring laser-induced graphene to a hydrogel film at cryogenic temperatures, stretchable graphene–hydrogel interfaces can be created for application in wearable and implantable electronics.

A large-angle twist between two bilayer graphene films makes a sensitive and broadband infrared–terahertz detector as a result of interlayer screening and a crystal field-induced bandgap.

The synthesis of conjugated aromatic molecules and polymers with tailored properties provides a useful range of materials for electronic devices.

A living catalyst transfer polymerization enables access to low dispersity polyphenylenes and ultimately to length-selective synthesis of graphene nanoribbons.
