Really looking forward to having Shuxia visit us for the physics colloquium this week. It's always great to hear more about the theory approach to understanding the often surprising behaviour of halide #perovskites.

Thus, whether initial excitations generate Wannier-Mott or of Frenkel type excitons is an important detail that I find deserves more attention in the community.

Simon Kahmann @skahmn.bsky.social · 03/04/2025

STEs certainly play a dominat role in many materials our community studies, but I have often felt that STE is used as a catchall term which obscures a lot of information. For example, I think it makes a big difference whether an exciton is initially delocalised before self-trapping or not.

Simon Kahmann @skahmn.bsky.social · 03/04/2025

Ever since I started working on broadband luminescence in 2D perovskites, I have been intrigued by all the different origins and phenomena at play. The entire concept of self-trapped excitons was new to me and it was exciting to discover that the are responsible in (PEA)2PbI4 and related materials.
