A new and versatile combinatory nanofabrication technique called the oblique angle co-deposition is developed to generate a library of nanomaterials with different morphology and structure. Using the Cu-Fe2O3 system as an example, by carefully characterizing the vapor plumes of the source materials, a composition map can be generated to design the locations of different substrate holders. The resulting nanostructures at different locations show different thickness, morphology, crystallinity, and composition. In addition, maps of different structural parameters are established, which can be used to correlate their properties. By further oxidizing or reducing the composite nanostructures, the properties of the nanostructures such as band gap, photocatalytic performance, and magnetic properties can be easily linked to their composition and other structural parameters. Optimal materials for photocatalytic and magnetic applications are efficiently identified. It is expected that the oblique angle co-deposition and its variations could become a powerful combinatory nanofabrication technique for nanomaterial survey.
