Figure 3From: Magnetoresistance in Sn-Doped In2O3NanowiresResistance-temperature dependent measurements taken atB= 0 and using different current levels (only 1 μA is shown). In the high temperatures range, the nanowires exhibit a positive temperature coefficient of resistance and a weak temperature dependence. The inset shows the results for other and larger samples showing the same behaviorBack to article page
