  • During photoionization, the recoil of the atom or molecule due to the ejected electron can subtly alter the observed photoelectron and Auger spectra from expectations. Here, the authors study Auger emission from isolated neon atoms and see a Doppler shift in the spectrum resulting from translation recoil.

  • Stacking layers from different van der Waals materials can enable rotational symmetry breaking and engineering of the electronic band structure. Here, the authors report the observation of the creation of anisotropic minigaps and the appearance of flat bands at the valence band maximum in monolayer MoS2-black phosphorus heterojunctions.

  • The ability to gather experimental access to the kinetics of charge carriers is central in semiconductor physics. The authors utilize hard x-ray radiation from a synchrotron source to probe the charge transfer dynamics in the attosecond regime in layered GeSe, thus providing crucial information for future photonic and optoelectronic devices.

  • Identifying a universal magnetic ground state across the iron-based superconductor family may help to propose a universal pairing glue responsible for unconventional superconductivity in these intriguing materials. Here, the authors discover an antiferromagnetic stripe order that appears as a precursor to superconductivity in pressured BaFe2Se3, suggesting that the presence of magnetic fluctuations from the stripe order may hold the key to the superconducting pairing of the iron-based superconductors.
