Tailoring Hot Exciton Dynamics in 2D Hybrid Perovskites through Cation Modification

Daniel B. Straus, Sebastian Hurtado-Parra, Natasha Iotov +5

We report a family of two-dimensional hybrid perovskites (2DHPs) based on phenethylammonium lead iodide ((PEA)${}_2$PbI${}_4$) that show complex structure in their low-temperature exci…
