A melt-processable 2D Cd-based ferroelectric semiconductor with a promising X-ray response.
2D metal halide perovskites integrating ferroelectricity and solution processability are highly sought-after for advanced optoelectronics, yet concurrent realization of these features, particularly for lead-free systems, poses a persistent challenge. Here, we report a solution-grown 2D cadmium perovskite, (CHA)2CdBr4 (...
