報(bào)告摘要：
Recently, two-dimensional (2D) materials have attracted significant attention due to their novel physical and chemical properties, and potential applications in microelectronics and optoelectronics devices. Among those 2D materials, bismuth telluride (Bi2Te3) presents an interesting candidate material for realizing high performance infrared nanosensors as a result of its favourable bandgap and potential high electron mobility as a result of its topological insulator properties. In this work, we will review our recent effort on studying the controlled growth of 2D Bi2Te3 nanostructures, and exploring their applications in flexible near-infrared (NIR) sensors. The flexible NIR sensors based on 2D Bi2Te3 nanostructures present excellent device performance in comparison to those reported in literature for other 2D nanomaterial-based NIR sensors, including photoresponsivity, specific detectivity and photoconductive gain. Furthermore, the device performance shows no obvious degradation after bending for a few hundred times, indicating their great flexibility. These findings indicate that 2D Bi2Te3 nanostructures present great potential for fabricating high performance flexible NIR sensors.
