Abstract: The selective detection of two different gases, NO(2) and C(2)H(5)OH, has been achieved using a p-type Co(3)O(4)-decorated n-type ZnO nanowire (NW) network sensor. The gas selectivity was explained by the catalytic effect of nanocrystalline Co(3)O(4) and the extension of the electron depletion layer via the formation of p-n junctions.
