Nature Nanotechnology, Published online: 22 April 2024; doi:10.1038/s41565-024-01652-yAcid-etching-driven nanosurface reconstruction of perovskite quantum-dot pure-red LEDs facilitates a peak external quantum efficiency of 28.5% and a half-lifetime of 30 h at 100 cd m−2 luminance, enabling highly efficient solution-processed active-matrix perovskite...

Nature Nanotechnology, Published online: 22 April 2024; doi:10.1038/s41565-024-01653-xA simple manipulation of an electrolyte’s glass transition enables nanoresolved electrochemical ion implantation doping in a variety of polymeric semiconductors.

Nature Nanotechnology, Published online: 19 April 2024; doi:10.1038/s41565-024-01650-0Plasmonic tunnel junctions integrated with a monolayer semiconductor are found to emit photons with energies exceeding the input electrical potential. This peculiar phenomenon is ascribed to being triggered by inelastic electron tunnelling dipoles inducing optically...
