    Abstract

    Due to the requirements for large-area, uniform films, currently transition metal dichalcogenides (TMDC) cannot be used in flexible transistor industrial applications. In this study, we first transferred chemically grown large-area WSe<inf>2</inf> monolayer films from the as-grown sapphire substrates to the flexible plastic substrates. We also fabricated electric double layer transistors using the WSe<inf>2</inf> films on the plastic substrates. These transistors exhibited ambipolar operation and an ON/OFF current ratio of ∼10<sup>4</sup>, demonstrating chemically grown WSe<inf>2</inf> transistors on plastic substrates for the first time. This achievement can be an important first step for the next-generation TMDC based flexible devices.
