Original Abstract

MOSFET (Metal Oxide Semiconductor Field-Effect Transistor) sensors are based on a triple layer structure consisting of a catalytic gate metal, an insulator (oxide) and a semiconductor layer. Adsorbed hydrogen molecules on the metal surface dissociate and diffuse to the metal-oxide interface where they produce a change in the electrical properties of the transistor, which can be correlated to the hydrogen concentration in the ambient atmosphere. The performance of 2 identical commercially available MOSFET has been tested in terms of their accuracy, measuring range, cross-sensitivity to CO, as well as the influence of ambient temperature, pressure and relative humidity on their response. Results are compared with those obtained previously for a number of other sensor types.
