Observation of polaronic state assisted sub-bandgap saturable absorption

Observation of polaronic state assisted sub-bandgap saturable absorption

In soft-lattice lead-halide perovskites, the polaronic effects involving stabilization of localized charge character by structural deformations and polarizations have an important effect on the properties of functional materials such as the band gap, which has attracted considerable investigations....
