Effect of Varying the Semiconducting/Metallic Tube Ratio on the Performance of Mixed Single-Walled Carbon Nanotube Network Gas Sensors

Figure 9

Comparison of the (a) sensitivity and (b) response time before and after plasma treatment for the unenriched 66% and 90% enriched SWCNT-network sensors. The response time is the 90% point of the final steady-state resistance. The error bars represent the standard deviation of measurements performed for at least three independent sensors.
