Vortex-Beam Transient Absorption Microspectroscopy Resolves Ultrafast Free-Exciton and Polaron Diffusion in 2D Perovskites
Ju-Young Kim, Anirban Mondal, Gi Rim Han +4
The authors introduce a vortex‑beam transient absorption microspectroscopy (VTAM) technique that encodes spatial diffusion into the pump‑probe signal, allowing sub‑picosecond measu…

Ultrafast exciton polaron dynamics in 2D Ruddlesden Popper lead halide perovskites
Anirban Mondal, Kwang Jin Lee, Seungmin Lee +5
Two dimensional Ruddlesden Popper (2D) RP hybrid perovskites exhibit substantially higher chemical and structural stability than their three dimensional (3D) counterparts, position…
