Production of Nanodots by Ion Sputtering on Mechanical Polished (110) Si-Substrates

Ballesteros C., Rodríguez T., Rodríguez T., Universidad Carlos III de Madrid, ES

We report a new method to deposit Cu nanocrystals by 5kV Ar+ ion sputtering of Cu metallic ribbons at glazing incidence, 8º, on top of (110) Si-substrates mechanical polished down to a 0.1 μm finish. [...]

Microstructure Changes Induced by Low-energy High-temperature Nitrogen Ion Implantation on Vanadium-Titanium Alloys

Varela M., García J.A., Rodríguez R., Ballesteros C., Univ. Carlos III de Madrid, ES

A detailed structural characterization of unimplanted and low-energy, nitrogen implanted V5at.%Ti alloy is presented. The alloys were produced by repeated arc melting in a high-purity He atmosphere. Samples were nitrogen-implanted at 1,2 kV and 1 [...]
