  • A full theoretical understanding of plasmon decay into hot carriers will help in applications such as solar cells or photocatalysis. Here, the authors present a quantized plasmon model to calculate the hot-carrier distribution from plasmon decay and show its sensitivity to the band structure of the host metal.

  • Topological materials confined in 1D could transform computing technology, but their crystallization is poorly understood. Here, the authors demonstrate template-based synthesis of 1D nanowires, revealing diameter-dependent phase selectivity.

  • Researchers demonstrate a persistent spin helix in an organic–inorganic hybrid ferroelectric halide perovskite whose layered nature makes it intrinsically like a quantum well. They demonstrate a switchable spin-polarized band structure via an intrinsic ferroelectric field.

  • Halide perovskites exhibit largely tunable spin-orbit interactions, and long carrier lifetimes, making this class of materials promising for spintronic applications. Here, Xu et al present first principles calculations to determine the spin lifetimes, and identify the dominant spin-relaxation and dephasing processes.

  • Understanding the role of plasmon excitation is crucial for the realization of hot carrier devices. Here, the authors report internal quantum efficiency measurements in photoexcited gold gallium nitride Schottky diodes and elucidate the roles of surface plasmon excitation, hot carrier transport, and carrier injection in device performance.

  • First-principles calculations can help design and understand the behaviour of quantum technologies, but this requires the development of accurate methods to predict material properties. Here the authors present a method for calculating the spin-phonon relaxation time of general systems, a key quantity for spintronic devices.

  • Plasmons in sub-nm cavities can enable chemical processes within plasmonic hotspots. Here the authors use surface-enhanced Raman spectroscopy to track hot-electron-induced chemical reduction processes in aromatic molecules, thus enabling observation of redox processes at the single-molecule level.

  • Knowledge of the electron-gas dynamics in nanometric hot spots is of importance for hot-carrier technologies. Here Lozan et al. present a theoretical and experimental analysis of the spatio-temporal dynamics of hot electrons in a nano-focusing surface-plasmon polariton taper.

  • Quantitative understanding of the spatial localization of hot carriers has been elusive. Here Corteset al. spatially map hot-electron-driven reduction chemistry with 15 nm resolution as a function of time and electromagnetic field polarization for different plasmonic nanostructures.

  • Photo-excited gold nanoparticles are shown to provide ultrafast and efficient hot-hole injection to the valence band of p-type GaN, substantially altering hot-electron dynamics in the nanoparticles and forming a basis to design hot-hole-based optoelectronics.

  • This work studies luminescence from monocrystalline gold flakes down to 13 nm thick. It reveals this signal is photoluminescence, with signals reproduced by density functional theory, resolving a decade-old puzzle.
