Shining light on excited-state dynamics in perovskite materials
Through a close collaboration between experimentalists at University of California Berkeley and theorists in Physics and Chemistry of Materials (T-1), the Center for Nonlinear Studies (CNLS), and Center for Integrated Nanotechnology (CINT) at LANL, researchers have performed femtosecond transient absorption and density functional theory simulations to probe the excited-state dynamics of hybrid perovskite MAPbI3 and found evidence for coherent skeletal vibration dynamics that lead to formation of a polaron state underscoring charge separation.
