Interference-Enhanced Raman Scattering of Very Thin Titanium and Titanium Oxide Films

Abstract

The Raman spectra of very thin evaporated films (∼6 nm thick) of metallic titanium and oxidized titanium are obtained with a new technique called interference-enhanced Raman scattering. The results indicate that titanium films exhibit a crystalline hcp structure while the titanium oxide has an amorphous structure with local atomic bonding configurations similar to those in crystalline ${\mathrm{Ti}}_2$ ${\mathrm{O}}_3$.
