DOIAbstract
ZnO nanorod assemblies were grown by plasma-enhanced chemical vapor deposition on polycrystalline Al(2)O(3) at 200-300 degrees C, resulting in urchin-like 1-D ZnO NR arrays with a strong c-axis orientation. Their outstanding gas sensing responses and very low detection limits highlight the potential of the present systems in the production of high efficiency chemical sensors for a variety of applications
