Heating-up Synthesis of MoS2 Nanosheets and Their Electrical Bistability Performance

Molybdenum disulfide (MoS2) nanosheets were synthesized by using a simple heating -up approach, in which 1-dodecanethiol (DDT) was used not only as a sulfur source but also as the surface ligand. The sheet -like morphology was confirmed by the transmission electron microscopy (TEM) and atomic force microscopy (AFM) results, and the X-ray diffraction (XRD) patterns and Raman spectrum were employed to characterize the structure of the as -synthesized MoS2 nanosheets. The as -obtained MoS2 nanosheets blending with a polymer could be used to fabricate an electrically bistable device through a simple spin -coating method, and the device exhibited an obvious electrical bistability in the I-V curve. The charge transport of the device was discussed based on the organic electronic models.
