Boosting the Performance of Epitaxial Perovskite Microstructures by Surface Passivation
Advanced Optical Materials, EarlyView.Surface passivation is applied to epitaxial perovskite structures. Improvements are obtained in respect to luminescence intensity and decay time, as well in respect to photodetection and lasing. Highlight results include photoluminescence transients that are limited only by carrier diffusion and a record low laser threshold for microcrystal‐based ...
