    • The localized band bending (or the space-charge region) associated with the Schottky contact can extend into the nanowire region under high reverse biases. However, the photocurrent spatial profile remains unchanged under various biases (not shown here), indicating that the hole transport is diffusion in nature

    • This value is larger than the nominal NSOM aperture size (100-150 nm), probably due to the finite distance between the NSOM probe and nanowire surface (Ref.): the "wear and tear" of the NSOM probe during the scan might also be a factor

    • If, alternatively, the surface states arise due to the presence of surface adsorbates, a diameter-independent surface electronic structure would lead to a constant S for different diameters, opposite to our observations. Therefore, the argument of a diameter-dependent surface electronic structure is still valid
