Abstract

Recent research on hybrid organic–inorganic perovskites has greatly advanced the fields of photovoltaics, photodetection, and light emission. The emergence of piezotronics and piezo-phototronics has led to tremendous high-performance devices that are based on piezoelectric materials. Although many p...
