Ultrathin SnS nanobelts were synthesized via physical vapor deposition (PVD). Furthermore, high performance near-infrared (NIR) photodetectors based on SnS nanobelts showed an excellent photoresponsivity of 300 A W-1 under 800 nm light illumination with an external quantum efficiency of 4.65 x 10(4)% and a detectivity of 6 x 10(9) Jones, as well as fast rise and decay times (tau(rise) = 36 ms and tau(decay) = 7 ms), suggesting a promising future for the utilization of the SnS nanobelts in practical NIR light sensors.
