A.C photoresponse results. a Schematic showing the A.C photocurrent for different measurement conditions. b A.C responsivity of the half-patterned (red), full-patterned (green) and unpatterned (blue) graphene detectors for the positive (solid) and negative (dashed) offsets (0.25 V) at f = 20 Hz. c A.C responsivity as a function of frequency for VG = −2V. The crosshair shown in dashed lines corresponds to the cut-off frequency
