Abstract

Using the X-ray Photoelectron Spectroscopy (XPS), Ti/Co₃O₄ interface was inves tigated. Cobalt was oxidized ex-situ and a thin layer of Titanium deposited by Physical Vapor Deposition (PVD) on the Co3O4 substrate. The Ti/Co₃O₄ sample was annealed for several thickness of Titanium with varied annealing Temperatures. The interface of Ti/Co₃O₄ was characterized by XPS. Titanium gets oxidized into titanium TiO₂and other suboxides), whilst Co3O4 gets reduced to CoO and elemental Cobalt. This study probed deeper into the threshold thickness for Ti beyond which it gets no more oxidized while closely examining the temperature effect of physical and chemical change at the interface. We will also look into details the effect of annealing and Titanium thickness on the Physi cal and structural changes at the interface
