Antimony　sulfide　(Sb2S3)　photodetectors　(PDs)　possess　extensive　application　prospects.　Efficient　carrier　transport　of　a　PD　significantly　affects　the　detectivity　and　response　speed.　Herein,　we　propose　an　all-inorganic　self-powered　Sb2S3　PD　based　on　vertical　TiO2　nanorods　(NRs).　The　spray-coated　15-nm　TiO2　thin　film　as　a　seed　layer　ensures　the　growth　of　compact　vertical　TiO2　nanorod　arrays　by　the　hydrothermal　method.　One-dimensional　TiO2　nanorods　facilitate　photocarrier　separation　and　transport　to　enhance　device　performance.　Ultimately,　the　Sb2S3　PD　achieves　a　responsivity　of　0.29　A/W,　a　specific　detectivity　of　3.37　x　1012　Jones,　and　a　response　time　of　7.8　mu　s,　showing　great　potential　in　commercial　applications.　(c)　2024　Optica　Publishing　Group.　All　rights,　including　for　text　and　data　mining　(TDM),　Artificial　Intelligence　(AI)　training,　and　similar　technologies,　are　reserved.
