Recent Progress in Ohmic/Schottky-Contacted ZnO Nanowire Sensors

Figure 13

(a) 3D graph depicts the current response of the ZnO NW humidity sensor to strain and relative humidity at a bias voltage of 2.8 V. (b) Absolute current response to different compressive strains, with relative humidity ranging from 15.0% to 42.8%. (c) Absolute current response to different relative humidity, with compressive strains ranging from −0.00% to −0.22%. (d) Indicating the relative changes of current with respect to the value at 42.8% RH, under different compressive strains ranging from −0.00% to −0.22%. (e) Indicating the relative changes of current with respect to the value at 0.0% strain, under different RHs ranging from 15.0% to 42.8% [78]. Copyright 2014, Springer.
