Abstract
Surface and interface engineering have shown broad application prospect in energy conversion. Mo2C-C/Sb2S3 composites have been synthesized by coupling Mo2C-C composites and Sb2S3 nanowires with coupling agent. The performance of the devices has been investigated. Under irradiation by light source, the device showed better electrical contact, fast response speed (rise time 0.135[Formula: see text]s, decay time 0.132[Formula: see text]s) and larger on/off ratio ([Formula: see text]) than the device which assembled by mechanical mixing ([Formula: see text]) and pure Sb2S3 nanowires (47), respectively. The performance has been enhanced by modifying the surface and interface of materials. This approach provides a new idea to enhance the high-performance photodetectors and other inventive optoelectronic devices.
