(Color online) (a) Low-magnification scanning electron microscopy (SEM) image of the as-synthesized nanowires. Scale bar: . Inset: high-magnification SEM image of a single nanowire. Scale bar: . (b) Low-magnification TEM image of a :Sb nanowire. Scale bar: . Top inset: SAED pattern of the :Sb nanowire, indicating the [101] growth direction. Bottom inset: HRTEM image the same nanowire. Scale bar: . (c) Comparison of the current-voltage characteristics using four-probe and two-probe configurations for a nanowire device. Inset: SEM image of the device. Scale bar: . (d) Histogram of resistivities measured on 112 nanowire devices.
