N2 - Recently, molybdenum disulfide (MoS2) has become a popular material due to its unique electrical and chemical properties, and its use as a potential substitute for graphene. Herein, we report a new two-step method by utilizing thermal evaporation-sulfurization to synthesize MoS2 which possesses an innovative micro-ring structure. The average statistical values of the height, width and external diameter were 69 nm, 0.3 μm and 5.0 μm, respectively. Then the mechanism for the growth of such MoS2 micro-rings was proposed. A device based on the MoS2 micro-ring was prepared by electron beam lithography, and its electrical transport properties were determined at different temperatures.
