Adventures with Graphene, Phosphorene and Silicene: from Materials to Device Integration

Graphene, crowned with 2010 Nobel Prize in Physics, is a pioneer two-dimensional (2D) material featuring extraordinary electrical and mechanical properties for innovative devices. This talk will present new routes in scalable synthesis of high-quality graphene1-2 <> , clean delamination transfer3 and device integration4, which lead to probing intrinsic limit of physical and surface properties of graphene that conventional approaches cannot afford. Such developments have also delivered state-of-the-art electronics such as graphene touchscreens in smartphones on market and flexible RF devices on plastics with a record frequency of 25 GHz and reliability across many cycles of bending stress. Beyond graphene, phosphorene and silicene (emerging elementary 2D materials) made flexible electronics5 and field-effect transistor debut6, exhibiting ambipolar transport behavior with either a direct band-gap or greater gate modulation. 2D materials offer a great opportunity for both fundamental studies and practical applications in high-speed, low power-consumption, bendable/wearable consumer-electronics, sensors, and energy devices that will have a widespread impact on our society.
