Characterization of RF-sputtered ultra-thin WO3 films grown on TiO2 surface

Dobromir M., Manole A., Apetrei R., Luca D., Alexandru Ioan Cuza University, RO

We report on TiO2 and WO3/TiO2 bilayers thin films grown on amorphous and crystalline substrates, at room temperature by plasma-assisted sputtering. TiO2/WO3 ceramic targets were used in an RF magnetron discharge running in an Ar [...]

Fabrication and characterization of nano-structured ferromagnetic Ti1-xFexO2 thin films

Apetrei R., Negrila C., Macovei D., Dascaleanu V., Teodorescu C.-M., Luca D., Alexandru Ioan Cuza University, RO

Ti1-xFexO2, 300 nm thin films with x ranging between 0.0 and 0.6, have been fabricated by RF magnetron sputtering. Specimen characterization was done by XPS, AFM, XRD,UV-Vis spectrometry, MOKE, and XANES/EXAFS techniques. The AFM and [...]
