Trapped in the array: High-purity p-type CuO/n-type ZnO nanocomposites were prepared by Cu sputtering on columnar ZnO arrays obtained by plasma-enhanced chemical vapor deposition, followed by annealing in air. Preliminary gas-sensing tests revealed very attractive responses, along with the possibility of discriminating between oxidizing and reducing species.
