Table 1

Details containing the dimensions, the measured ON/OFF current ratios, and ideality factors of the NWs whose I–V curves are shown in Fig. 3a
Type Number Diameter (nm) Length (nm) ON/OFF current ratio Ideality factor (n)
p–n 1 160 250 168 1.8
p–n 2 155 290 125 1.7
p–n 3 230 277 50 2.0
p–i 145 280

The ON/OFF current ratios are calculated at ±1 volt
