Fig. 3: Persistent photocurrent density in the InSe/Gr photoanode.
From: Atomically thin photoanode of InSe/graphene heterostructure
a Current density as a function of illumination time for InSe with various thicknesses. Inset shows the observed Jmax as a function of the InSe thickness. b Photocurrent decay for InSe with various thicknesses. The time point at which the light ceased is defined as t = 0 for each sample. The red lines are the best fit using Eq. (2). c Temporal dependence of the bulk InSe/Gr anode with various NaOH concentrations.
