Photocurrent response curves, estimated photocurrent versus intensity, and calculated responsivity and gain versus intensity. (a) Photocurrent response curves under inter-band excitation (λ = 325 nm) with different intensities, (b) estimated steady-state photocurrent versus intensity, and (c) calculated responsivity and gain versus intensity measured at a bias of 0.1 V for the V2O5 NW with d = 800 nm and l = 2.5 μm.
