  • Monolayer graphene can support the quantum Hall effect up to room temperature. Here, the authors provide evidence that graphene encapsulated in hexagonal boron nitride realizes a novel transport regime where dissipation in the quantum Hall phase is mediated predominantly by electron-phonon scattering rather than disorder scattering.

  • Here, the authors report the realization of a sub-THz wireless data link based on a graphene-integrated optoelectronic mixer with a >96 GHz bandwidth, −44 dB upconversion efficiency and <0.1 mm2 footprint, providing an alternative approach for the realization of millimeter-wave transmitters.

  • Atomically thin materials offer unique opportunities for controlling electronic properties layer by layer. This study introduces a monolithically grown twistronic stack of monolayer and bilayer graphene, revealing that structural asymmetry can induce a band gap in bilayer graphene without external fields.
