FIG. 1.

(a) SEM image of the aligned InSb NWs bridging the source-drain electrodes after ac dielectrophoresis alignment. (b) Enlarged SEM image of an individual suspended InSb NW between electrodes. (c) Two terminal source-drain current-voltage (Ids−Vds) characteristic curve of the InSb NWs sensor device exposed to dry air.

Image of FIG. 2.
FIG. 2.

(a) Dynamic response (ΔR/R0%) and (b) calibration curve for NO2 of InSb sensors to varying concentrations of NO2 in dry air (the data point is an average of the response of four sensors after 50 min exposure and the error bar represents ±1 S.D.).

FIG. 3.

(Color online) (a) Response and corresponding (b) Elovich plots of relative resistance variation of InSb NWs sensor to 4 ppm NO2 at different temperatures.
