Abstract

The selective detection of two different gases, NO₂ and C₂H₅OH, has been achieved using a p-type Co₃O₄-decorated n-type ZnO nanowire (NW) network sensor. The gas selectivity was explained by the catalytic effect of nanocrystalline Co₃O₄ and the extension of the electron depletion layer via the formation of p–n junctions.
