Characterization of sputter deposited Co doped TiO2 films


EMSL Project ID
6910

Abstract

Sputter deposited Co:TiO2 films are of interest as part of the joint NSF Oxide Spintronics project between UW and PNNL. The films were sputtered onto LaAlO3 substrates, and have shown enhanced ferromagnetic behavior at room temperature upon annealing. It is the focus of my current research to determine if the increased moment/Co atom is due to clustering of the Co atoms in the films, or whether there is a uniform distribution throughout the film. Characterization methods I would like to use for my samples are TEM and RBS, with the goals of determining the clustering/uniformity of Co on samples both as-deposited and after a high vacuum anneal (via TEM imaging), and atomic % Co as a function of film depth (via RBS).
