Abstract
A gas detection device is provided having a substrate. A sensing element is coupled to the substrate and constructed and arranged to sense a target gas. A top surface is positioned on the sensing element opposite the substrate. A dopant is disposed within the sensing element. The dopant enhances the ability of the sensing element to sense the target gas. An electric field is applied to the dopant to constrain the dopant at or near the top surface of the sensing element.
