Transport and the pulse-coincidence measurement of a bi-metal contacted graphene photodetector.

(a) Two-probe conductance as a function of the gate voltage. Inset: The optical micrograph of the device. (b,c) Photoresponse measured using the pulse-coincidence technique as a function of the delay time at p-doped (b) and n-doped (c) regions; legends indicate the gate voltage in volts. The temperature is fixed at T = 50 K. The unit scale of the y-axis is the same for all curves.
