“…However, the demonstration of nonlinear quantum hydrodynamics, such as superfluidity and Čerenkov flow, which is a consequence of the renormalized elementary excitation spectrum, remains elusive in halide perovskites. Here, using homogenous halide perovskites single crystals, we report, in both one- and two-dimensional cases, the complete set of quantum fluid phase transitions from normal classical fluids to scatterless polariton superfluids and supersonic fluids—all at room temperature, clear consequences of the Landau criterion. …”

“…This study determines the effects of annealing treatment on the structure and the optical and electronic behaviors of the mixed (FAPbI(3))(1−x)(MAPbBr(3))(x) perovskite system. The experimental results reveal that (FAPbI(3))(1−x)(MAPbBr(3))(x) (x ~ 0.2) is an effective light-absorbing material for use in inverted planar perovskite solar cells owing to its large absorbance and tunable band gap. …”
