The role of lattice degrees of freedom in the ultrafast optical response of lead-halide perovskites (A)PbBr3.
ORAL
Abstract
We use ultrafast laser spectroscopy to study hybrid organo-metallic and all-inorganic lead halide perovskites. By analyzing the time resolved response of the material we demonstrate the importance of lattice degrees of freedom for the strong nonlinear response in lead-halide perovskites.
