Quasi-2D Metal Halide Perovskite Thin Films This cover illustrates superfluorescence in quasi-2D metal halide perovskite thin films. Optical excitation drives carrier synchronization and a collective burst, underpinning the superfluorescence–amplified spontaneous emission–spontaneous emission phase diagram and quantum theoretical simulations reported in this work. More details can be found in the Research Article by Tze Chien Sum, Subodh G. Mhaisalkar, Annalisa Bruno, and co-workers (DOI: 10.1002/adma.202518842).
