The 20th century ushered in the Information Age with the silicon electronics industry’s aggressive and persistent scaling down of the Complementary Metal-Oxide-Semiconductor Field-Effect Transistors’ (MOSFET) dimensions. However, we now face the impending stall of Moore’s Law and must find alternative materials and novel device concepts which may augment commercial silicon technology for enabling high performance and low power consumption. During the last decade, tremendous research efforts have been focused on two-dimensional (2D) materials due to their rich physics and great potentials for many applications. Accordingly, in this talk we present some experimental results of 2D materials electronics, including piezotronics[1], tunnelling field effect transistor [2], vertical hot electron transistor [3], photodetector [4], magnetic property for spintronics [5], quasi-heterojunction bipolar transistor [6]，quantum tunnelling behaviour for tunnelling transistor [7] and high performance 2D field effect transistor [8]. Our results suggest that electronics based on 2D materials could potentially lead to energy generation and low power dissipation for future device applications.
