In this work, copper cobalt sulfide (CuCo2S4 or carrollite) thiospinel nanocrystals were synthesized by a hot-injection method, and detailed electrical and optoelectronic characterizations were performed in a Schottky device. The synthesized nanocrystals were used as an interfacial layer between the Au metal and p-Si semiconductor to obtain an Au/CuCo2S4/p-Si device. The structural and morphological characterizations confirmed the crystallinity, nanostructure and composition of the CuCo2S4 nanocrystals. The I-V and C-V measurements were employed to characterize the Au/CuCo2S4/p-Si device for various illumination intensities. The obtained device exhibited good rectifying and photodiode properties as well as good photocapacitance. The Au/CuCo2S4/p-Si device can be used and improved for optoelectronic applications.eninfo:eu-repo/semantics/openAccessCuco2s4CarrollitePhotodiodeOptoelectronic PropertiesHot-Injection MethodSchottky-Barrier DiodesSeries ResistanceElectrical CharacterizationV CharacteristicsInterface StatesHighly EfficientC-VLayerParametersCatalystsArticle10.1007/s11664-019-07841-z2-s2.0-85075686146
