Nanostructured Functional Thin Films Through Vapor Phase Deposition

The ability to control the physicochemical properties of surfaces is important for many areas such as biomedical or optical coatings, sensors, and catalyst supports. We have been developing nanostructured functional thin films based on oblique angle deposition (OAP) method for these applications without using any lithography techniques or template materials. These films posses’ novel properties which could be potentially manipulated based on the growth conditions and the deposition parameters. The surface‐to‐volume ratio of structured films is very high and the available surface area increases by more than two orders of magnitude in relation to the bulk film. We are studying nucleation, crystallinity and growth as well as pore size and geometries of nanostructured thin films. Our technique opens a new wealth of applications to assemble many possible combinations of organic or metallic precursors that have desired functional groups or plasmonic features for creating novel thin films. In this presentation, we will describe our process for creating nanostructured thin films and present results concerning their applications.
