    Abstract

    Molybdenum disulfide (MoS 2) thin-film transistors were fabricated with ion gel gate dielectrics. These thin-film transistors exhibited excellent band transport with a low threshold voltage (<1 V), high mobility (12.5 cm 2/(V ·s)) and a high on/off current ratio (10 5). Furthermore, the MoS 2 transistors exhibited remarkably high mechanical flexibility, and no degradation in the electrical characteristics was observed when they were significantly bent to a curvature radius of 0.75 mm. The superior electrical performance and excellent pliability of MoS 2 films make them suitable for use in large-area flexible electronics.
