SEM image, band diagram,IDS-VGS, andIDS-VDScurves. (a) SEM image (scale bar = 1 μm) of one representative NW FET; the inset shows the schematic illustration of the back-gated FET configuration. (b) Band diagram of the NWs contacted with Ni source/drain electrodes. (c) IDS-VGS curves and (d) IDS-VDS curves of the NW FET.
