Porous thin films prepared by Physical Vapor Deposition at oblique angles present a series of outstanding characteristics that make them unique candidates for the synthesis of nanostructural materials and the development of advanced devices. [1] Last advances of the synthesis of this kind of thin films and related nanosculptured structures, either by e-beam evaporation or magnetron sputtering, will be revised paying attention to the physical mechanisms that control their growth and give rise to their high porosity, nanocolumnar microstructure and in-plane asymmetry. Their use as template for the synthesis of composite photonic materials, as optofluidic sensors or as electrodes for fuel and photovoltaic cells are examples of possible applications of this type of nanostructure materials that will be revised in this talk.
