An ultrasensitive phototransistor was fabricated based on K-intercalated MoO3 single nanowire. Devices with ultrafast photoresponse rate, high responsivity, and broad spectral response range were demonstrated. Detailed analysis of the charge transport in the device revealed the coexistence of both t...
