Figure 5. (A) ABPE plots; (B) Chopping J-t curves; (C) EIS Nyquist plots at 1.23 V vs. RHE under dark conditions; (D) OCP curves of the GaAs/MoS2 photoanodes with different MoS2 thicknesses. GaAs: Gallium arsenide; ABPE: applied bias photon-to-current efficiency; J-t: current density-time; EIS: electrochemical impedance spectroscopy; RHE: reversible hydrogen electrode; OCP: open-circuit potential.
