title = " High-Performance 2D MoS 2 Phototransistor for Photo Logic Gate and Image Sensor ",
abstract = " Two-dimensional (2D) MoS 2 is a representative n-type transition-metal dichalcogenide (TMD) semiconductor that has great potential for future nanoscale electronic and optoelectronic applications. Here, we report a high-performance MoS 2 phototransistor that exhibits a photoresponse in the 400-700 nm range with the maximum responsivity of over 1 × 10 4 A/W. As a more sophisticated optoelectronic application than a simple unit device, it is implemented in a photoinverter (NOT logic gate) connected to an external resistor, which clearly shows photoinduced static and dynamic characteristics. Furthermore, we demonstrate a prototype visible imager using the MoS 2 photoinverter as imaging pixels as an excellent example of advanced developments in an optoelectronic system based on the 2D semiconductors.",
