Constructing high-quality 1D nano/microwire hybrid structure for high-performance photodetectors based on CdSe nanobelt/perovskite microwire.

ABSTRACT: All-inorganic perovskite CsPbBr₃ is considered as a promising photoelectric material due to its high environmental stability and excellent photoelectric properties. Constructing low-dimension hybrid structures by combining CsPbBr₃ with semiconductor materials have recently attracted particular attention because they may bring new functionalities or generate synergistic effects in optoelectronic devices. Herein, the high-quality 1D CdSe nanobelt (NB)/CsPbBr₃ microwire (MW) photodetectors are designed first time, which exhibit excellent performance as integrating I _on/I _off ratio of 5.02 × 10⁴, responsivity of 1.63 × 10³ A/W, external quantum efficiency of 3.8 × 10⁵% and detectivity up to 5.
