Copper oxide nanowires (NWs) were prepared grown by thermal oxidation of metallic Cu thin layer deposited by RF sputtering on various substrates. A strong relation between oxidation parameters and morphology has been detected, and thus optimal growth parameters were found. The preliminary response of this alternative p-type sensing material, using nanowire's mat-based device, to various oxidizing and reducing target gases has been evaluated, in order to corroborate the functional properties of the CuO NWs as potential sensing material under certain conditions. © 2011 Published by Elsevier Ltd.

Abstract
Copper oxide nanowires (NWs) were prepared grown by thermal oxidation of metallic Cu thin layer deposited by RF sputtering on various substrates. A strong relation between oxidation parameters and morphology has been detected, and thus optimal growth parameters were found. The preliminary response of this alternative p-type sensing material, using nanowire's mat-based device, to various oxidizing and reducing target gases has been evaluated, in order to corroborate the functional properties of the CuO NWs as potential sensing material under certain conditions. © 2011 Published by Elsevier Ltd.File in questo prodotto:
