TiO2 Nanotube Arrays doped with iron are anticipated to exhibit multifunctional behavior that combines effects from electronic charge, magnetic spin and optical response. Properly engineered, these materials hold promise for potential application in devices to efficiently absorb and transfer solar energy and/or to process data with increased speed, precision and accuracy. We investigated the correlations of the morphology, crystallinity, crystal structure, electronic structure and magnetic properties of electrochemically-anodized TiO2nanotubes, with relevance to their functionality. This project was sponsored by the National Science Foundation under Grant No DMR-0906608.
