Chemical vapor deposition growth and photodetector performance of lead-free all-inorganic crystalline Cs₃Sb₂X₉ (X = I, Br) perovskite thin films

Abstract

Lead-free inorganic halide perovskites are non toxic and stable with unique properties making them suitable for many optoelectronic devices. We fabricated photodetectors with their thin films which demonstrated excellent photodetection performance.
