Abstract
Oxide semiconductor gas sensors with high response, rapid responding/recovering speed, selectivity, and low humidity dependence are designed by controlling the sizes, dimensions, morphologies, assembled configurations, nano-porosities, p-n junctions and surface modification of oxide nanostructures. The contribution consists of hierarchical and hollow nanostructures for highly sensitive and rapid responding sensors, the enhancement of gas response and selectivity by surface modification of oxide nanostructures, gas sensors using nano-scale oxide p-n junctions, and the strategy to decrease humidity dependence of gas sensing characteristics.
