Single crystal nanostructures of semiconducting tin oxides have been fabricated and
characterized as sensing materials for implementation in an electronic nose. The nanowires
exhibit exceptional crystalline quality and a very high length-to-width ratio, resulting in
enhanced sensing capability as well as long-term material stability for prolonged operation.
A sensing device based on SnO2 nanowires has been fabricated and comparatively tested
in an array of chemical sensor with conventional thin film sensing device. Preliminary …
