One Step

A bottom-up water-based solution-process method was developed for atomic layered MoS2 with a one-step annealing process and no sulfurization. The chosen MoS2 precursor is water soluble and was carefully formulated to obtain good coating properties on a silicon substrate. The coated precursor was annealed in a furnace one time to crystallize it. This method can obtain a large and uniform atomic layer of 2D MoS2 with 2H lattice structure. The number of atomic layers (4–7) was controlled through the precursor concentrations and showed good uniformity, which was confirmed by STEM and AFM. Four types of thin-film transistors (TFTs) were prepared from the solution-processed MoS2 on Al2O3 and SiO2 dielectric with either thermal evaporated Al or printed Ag source and drain electrodes. The best result shows an improved mobility of 8.5 cm2 V−1 s−1 and a reasonable on–off ratio of about 1.0 × 105 with solid output saturation.
