Role of the Material Electrodes on Resistive Behaviour of Carbon Nanotube-Based Gas Sensors for H 2 S Detection

Figure 3

Resistance curves as a function of time for H2S concentrations of 10, 20, 40, 60, 80, and 100 ppm (in N2), under standard conditions. The narrow peaks are due to the effect of the applied gate voltage coupled with a thermal shock (90°C), required for the complete desorption of the gas.
