High quality ultrathin single-crystalline SnSe2 flakes were synthesized under atmospheric pressure chemical vapor deposition for the first time. Constructed high performance photodetector based on the individual SnSe2 flake demonstrated a high photoresponsivity of 1.1×103 A·W-1, a high EQE of 2.61×105 % and superb detectivity of 1.01×1010 Jones, combined with the fast rise and decay times of 14.5 ms and 8.1 ms, respectively.
