FIG. 1.

Photocurrent maps under (a) forward and (b) reverse biased conditions. The insets to (a) and (b) show the schematic diagrams of the Fermi level as well as conduction and valence bands (CB and VB).

Image of FIG. 2.
FIG. 2.

(a) Photocurrent map with the shaded region and the dashed line representing the Schottky electrode and the nanowire, respectively; (b) the photocurrent spatial profile (open circles) along the nanowire plotted on a semilogarithmic scale with the solid line representing the fitting using a convoluted Gaussian-exponential function. Inset to (b) shows the cross-section photocurrent profile (open circles) taken perpendicular to the nanowire, with the solid line representing a Gaussian-peak fitting.

Image of FIG. 3.
FIG. 3.

Measured (solid circles) as a function of nanowire diameter. The dotted-dashed line represent the model with a constant ; the dashed lines represents the model with a diameter-dependent (solid line) shown in the inset plotted on a semilogarithmic scale.
