2D materials are promising semiconductors for integrated flexible electronics due to their excellent mechanical, optical and electronic properties. We have fabricated large-scale flexible and transparent electronics based on monolayer molybdenum disulfide field-effect transistors. Next, one of our most important projects is to use 2D materials (e.g., MoS₂, MoSe₂, WSe₂and WS₂) to explore and manufacture more flexible functional devices, such as flexible display driver, bionic electronic devices, optoelectronic devices, etc.
