AB - ABSTRACT: We demonstrate how combinatorial atmospheric pressure chemical vapor deposition (cAPCVD) can be used as a synthetic tool for rapidly optimizing the functional properties of thin-films; by analyzing the self-cleaning properties of tungsten doped anatase as an example. By introducing reagents at separate points inside the reactor, a tungsten/ titanium compositional gradient was formed and a diverse range of film growth conditions were obtained. By partially mixing the metal sources, a combinatorial film with a compositional profile that varied primarily in the lateral plane was synthesized. A combinatorial thin-film of anatase TiO2 doped with an array of tungsten levels as a solid solution ranging from 0.38 - 13.8 W: Ti atom % was formed on a single glass substrate. The compositional-functional relationships were understood through comprehensively analyzing combinatorial phase space; with 200 positions investigated by high-throughput methods in this study. Physical and functional properties, and their compositional dependencies, were inter-correlated. It was found that increases in photocatalytic activity and conductivity were most highly dependent on film crystallinity within the 0.38 - 13.8 atom % W: Ti doping regime. However, enhancements in photo-induced surface wetting were primarily dependent on increases in preferred growth in the (211) crystal plane.
