A survey of barrier formation and transport in MS and conducting MIS structures is presented and used to describe the hydrogen sensitivity of Pd/SiOx/Si structures. The presence of the interfacial oxide is shown to be necessary for the palladium diode to be sensitive to hydrogen. The sensitivity of highly responsive devices is shown to be due to Schottky barrier modification in the presence of hydrogen and not to an additional channel of transport caused by an increased interface state density in the presence of hydrogen.
