Abstract

The growth of Ag NPs decorated ZnO tip-like nanowires was obtained by a combination of the chemical vapor deposition and the micro-spraying methods. ZnO growth was analyzed by a two-level factorial experimental design with temperature, pressure, and zinc mass as the main parameters. The process of Ag NPs synthesis by electrolysis and their transport to the semiconductor surface using micro-spraying is presented in detail. By means of electrical and X-ray photoelectron spectroscopy, the potential of Ag NPs decorated ZnO tip-like nanowires to be used an active layer in gas sensor is demonstrated. [ABSTRACT FROM AUTHOR]
