Thiol-modified MoS2 nanosheets as a functional layer for electrical bistable devices

Molybdenum disulfide nanosheets have been synthesized by one-pot method using 1-ODT as sulfur source and surfactant . The structure, morphology and optical properties of samples were investigated by XRD , FTIR , Abs spectrum and TEM patterns. The XRD pattern indicated that the as-obtained MoS 2 belong to hexagonal system. The as-obtained MoS 2 nanosheets blending with PVK could be used to fabricate an electrically bistable devices through a simple spin-coating method and the device exhibited an obvious electrical bistability properties. The charge transport mechanism of the device was discussed based on the filamentary switching models.
