Abstract
A diffusion model is proposed for elucidating the effect of interelectrode distance modulation on conductance change of a nanomicrointegrated hydrogen sensor at room temperature. Both theoretical and experimental results showed a faster response upon exposure to hydrogen when sensor electrode gap was smaller. Also, a linear increase in the sensor sensitivity from 500 to 80 000 was observed on increasing the electrode spacing from 2 to 20 mu m. The improvement in sensitivity is attributed to the higher reactive sites available for the gaseous species to react on the sensor surface.
