  • Electron-phonon interaction is essential for understanding electronic and optical properties of lead halide perovskites. Here, using multiphonon Raman scattering and THz time-domain spectroscopy, the authors characterize the full phonon spectrum of CsPbBr3 and identify a single phonon mode that dominates electron-phonon scattering.

  • To understand the self-assembly of semiconductor nanocrystals, the formation mechanism of two-dimensional superlattices needs to be deciphered. Here the authors observe lead selenide nanocrystal organization at the ethylene glycol-air interface combining in-situ grazing-incidence small -and-wide-angle X-ray scattering, X-ray reflectivity and analytical calculations to obtain a three-dimensional picture of the adsorption geometry of the nanocrystals.
