Abstract
A hydrogen gas sensitive semiconductor sensor including a catalytic metal layer, a semiconductor layer and an insulator layer arranged between the catalytic metal layer and the semiconductor layer. The catalytic metal layer includes an outer surface and an inner surface including at least one hydrogen atom adsorption surface portion. Each hydrogen atom adsorption surface portion is arranged adjacent to the insulator layer. The surface area of the outer surface is at least 100% larger than the total surface area of all of the at least one hydrogen atom adsorption surface portion. A probe includes the sensor, A hydrogen gas detection system includes the sensor. Use of the sensor for detection of presence of and/or measurement of concentration of hydrogen gas in a gas sample.
