  • Ion migration is a plausible origin of material instability and photocurrent hysteresis in perovskite solar cells. Here, authors characterize photo-induced ion migration in perovskites by in situ laser illumination inside scanning electron microscope and observe long-range migration of halide ions.

  • The electronic structure of strongly correlated materials is highly sensitive to external perturbations such as photoexcitation, leading to exotic properties and phases. Here, the authors observe extremely slow hot carrier cooling and a photo-induced insulator-to-metal transition in a Mott insulator α-RuCl3 with scanning ultrafast electron microscopy.
