  • This Review examines conventional epitaxial growth of 2D van der Waals materials, focusing on in-plane single-crystal monolayer growth and out-of-plane homostructure fabrication. It covers nucleation and orientation control, quality control measures, and homogeneous multilayer and twisted homostructure growth techniques, providing systematic insights for on-demand fabrication of 2D van der Waals materials and their industrial device manufacturing.

  • Coexisting ferroelectricity and Chern insulators have been achieved using a doubly aligned magic-angle twisted bilayer graphene device. This device enables selective switching of topologically protected edge states and quasi-continuous ferroelectric levels that can support noise-immune neuromorphic computing applications.

  • Driven by carbon neutral targets, proton exchange membrane water electrolysis is becoming a hot technology due to its capability to convert fluctuating power into green hydrogen. Unfortunately, despite tremendous resources invested in fundamental research, only very few research outcomes have successfully translated into the development of industrial-scale electrolysers.

  • Here the authors present a pH-sensitive DNA origami nanoswitch that hides ligands for death receptors and displays them as a cytotoxic hexagonal pattern in acidic tumour microenvironments. This reduces tumour growth in a murine model of breast cancer with minimal on-target, off-tumour toxicity.

  • This Review explores adopting 2D semiconductors to overcome the scaling bottleneck of Si-based electronics. Recent trends and potential approaches for the development of 2D materials as a channel are discussed. Following this, the prerequisites, obstacles and feasible technologies for integrating contacts and gate dielectrics with 2D semiconductor-based channels are examined. The Review also provides an industrial perspective towards facilitating monolithic 3D integration.
