Direct Observation of Shallow Trap States in Thermal Equilibrium with Band‐Edge Excitons in Strongly Confined CsPbBr 3 Perovskite Nanoplatelets

Jacques-Edouard Moser, Etienne Christophe Socie, Andrés Burgos Caminal, Brener Rodrigo De Carvalho Vale

Lead halide perovskites exhibit great potential for light-emitting devices. Enhanced photoluminescence (PL) is obtained in perovskite materials of reduced dimensionalities due to the large exciton binding energy. However, as the nanocrystal size is reduced ...

Hot Carrier Mobility Dynamics Unravel Competing Subpicosecond Processes in Lead Halide Perovskites

Jacques-Edouard Moser, Andrés Burgos Caminal, Arun Aby Paraecattil, Ahmad Ajdar Zadeh Oskouei, Juan Manuel Moreno Naranjo, Aurélien René Willauer

The mechanisms behind the large photocarrier diffusion length and the outstanding photovoltaic performances of lead halide perovskites (LHP) are still debated. Hot carrier cooling and the formation of polarons are central to the charge separation process. ...
