Low dimensional semiconductors can be used for various electronic and optoelectronic devices because of their unique structure and property.In this work,one-dimensional Sb_2S_3 nanowires (NWs) with high crystallinity were grown via chemical vapor deposition (CVD) technique on SiO_2/Si substrates.The Sb_2S_3 NWs exhibited needle-like structures with inclined cross-sections.The lengths of Sb_2S_3 nanowires changed from 7 to 13 μm.The photodetection properties of Sb_2S_3 nanowires were comprehensively and systematically characterized.The Sb_2S_3 photodetectors show a broadband photoresponse ranging from ultraviolet (360 nm) to near-infrared (785 nm).An excellent specific detectivity of 2.1×10~(14) Jones,high external quantum efficiency of 1.5×10~4 %,sensitivity of 2.2×10~4 cm~2 W~(-1) and short response time of less than 100 ms was achieved for the Sb_2S_3 NW photodetectors.Moreover,the Sb_2S_3 NWs showed outstanding switch cycling stability that was beneficial to the practical applications.The high-quality Sb_2S_3 nanowires fabricated by CVD have great application potential in semiconductor and optoelectronic fields.
