The film's structural, morphological, topography, optical, and optoelectronic properties were investigated. Highly crystalline ternary chalcogenide CTS with tetragonal symmetry and 17 nm grain size is prepared. The 110 0 resistivity of the thin film increases up to 125 0 indicating a negative photoresponse under visible light excitation. The decrease in the photocurrent is also observed with Cu2SnS3/Au/Cu2SnS3 sandwich ternary chalcogenide structure at resistivities values from 31 to 35 0 and a Joule effect influence the presence of plasmonic Au nanoparticle interlayers involved a lower phonon disorder given a higher photoresponse effect as predicted from Urbach energy.eninfo:eu-repo/semantics/closedAccessPulsed Laser Deposition (Pld)Cu2sns3 (Cts) Thin FilmsNegative PhotoresponseUrbach EnergyObservation of negative photoresponse in joule-heated Au/Cu2SnS3 ternary chalcogenide thin film deposited by low energy pulsed laser depositionArticle1282-s2.0-85129478245Q1WOS:000797182200001Q210.1016/j.optmat.2022.112389
