Evidence of orbital mixing upon ionization via Cooper minimum photoelectron dynamics in epichlorohydrin. Experiment and Theory
L. Schio, M. Alagia, T. Moitra +18
A peculiar electron correlation effect, leading to orbital rotation upon ionization, theoretically predicted long ago, was never experimentally characterized. The effect is expecte…

The speed of sound and elastic properties of single crystals of inorganic and hybrid lead-free iodide perovskites obtained by femtosecond transient optical reflectivity
Giuseppe Ammirati, Patrick O Keeffe, Stefano Turchini +8
Optoelectronic devices operate under continuous thermal stress that may influence both long-term stability and optical properties of the active material. It is therefore useful to…

Hole Transfer Dynamics in Thin Films of Mixed-Dimensional Quasi-2D Perovskites
G. Ammirati, S. Turchini, F. Toschi +8
The understanding of charge transfer processes in mixed-dimensional quasi-2D perovskites is crucial for their application in high-performance photovoltaic devices. In this work, we…
