Conferencia: Nanostructured columnar thin films by magnetron sputtering: From fundamentals to devices.
In the first part of this talk, it will be shown that glancing angle deposition with magnetron
sputtering is a user-friendly route to fabricate nanocolumnar thin films (NCTFs) of metals
and metal-oxides in large areas of several square centimeters and above (scaling-up is
feasible) in a single-step process. This is in clear contrast to nanolithography techniques.
The development of the nanocolumnar morphology is the result of atomic shadowing,
atomic diffusion, and surface relaxation. In the second part of the talk, several
applications where NCTFs are of relevance will be described, discussing how and why
these nanostructured materials can be used in functional devices. For energy and
environment: as magnetic nanopillars with tailored properties, as nanostructured
surfaces with photo-induced self-cleaning properties, as nanostructured layers to
improve perovskite solar cells, and as black metal coatings in the visible range. For
biomedicine: as antibacterial coatings in orthopedic implants, as bioelectrodes for
electrical stimulation, as templates for chemical sensing by surface enhanced Raman
spectroscopy, and as working electrodes in the electrochemical detection of molecules.
Finally, for the aerospace industry: as nanostructured coatings that mitigate the
undesirable multipactor effect (which can prevent the correct performance of radio
frequency devices or even damage them).
