Tamm plasmon thermal emitters can provide efficient infrared emission, but are limited by design complexity. Now, the inverse design of Tamm modes facilitated by CdO films on aperiodic dielectric reflectors enables emission with an on-demand spectrum.
Thermoelectric materials can generate energy from a heat differential. This Review provides an overview of mid- to high-temperature thermoelectrics, their application in modules, and the issues that need to be addressed to enable commercial implementation of state-of-the-art materials.
The processes of metallic asperities moving across each other, which are decisive in most machinery, have been visualized at the atomic scale, revealing unexpected behaviour especially when under tensile stress.
A seemingly disordered network of nanowires governed by thermodynamics is used as the physical ‘reservoir’ in a memristive implementation of reservoir computing to process spatiotemporal information.
Scanning tunnelling microscopy experiments reveal a chiral charge density wave order underpinning the anomalous Hall effect in kagome lattice materials. Under pressure this charge order is suppressed, while superconductivity gets a boost.
Amorphous silicon shows abnormal tension–compression asymmetry, with much higher tensile yield strength than compressive yield. This discovery advances our understanding of plasticity in this and other similar amorphous materials.
A nanosensor probe that combines a tumour-targeting peptide, a diagnostic reporter and an imaging contrast agent enables early diagnosis, precision imaging, disease stratification and downstream therapeutic response monitoring of metastatic cancer.
The non-collinear spin structure and nontrivial Berry curvature of Mn3Ge give rise to a long-range supercurrent in superconductor–Mn3Ge–superconductor lateral Josephson junctions.
This Review provides an outlook on current understanding of the role of strain on the performance and stability of perovskite solar cells, as well as on tools to characterize strain in halide perovskite films and on strain management strategies.
Metallic behaviour from a two-dimensional hole gas has been observed in solution-processed organic crystals, giving hope for this state of matter to be used in next-generation large-area soft electronics.
Passivation of traps via site-specific surface doping allows access to the intrinsic properties of organic semiconductors and leads to the observation of electron atmospheres in organic crystals.
Using atomic-resolution electron microscopy to observe ion-exchange processes in atomically thin layered and restacked clays, substantially larger ion diffusion constants and moiré effects on ion dynamics are seen.
Centimetre-scale few-layer black phosphorus films have been grown on a mica substrate by pulsed laser deposition. The high crystalline quality and homogeneity of these films are promising for device applications.
