Abstract
A thin layer of hydrogenated amorphous silicon (a-Si:H) has been depos ited by PECVD on a NASICON (Na+ super ionic conductor) pellet used as a Na+-sensitive membrane. The conductivity of a-Si:H films has been ch aracterized and a dependence on the Na+ concentration has been noticed . This effect can be explained by a variation of the space charge at t he a-Si:H-NASICON interface. A new sensor based on this transducing mo de is proposed.
