Abstract :
We investigate the effect of chemical composition and residual stress on the mechanical properties of high-quality epitaxial TiNxOy films deposited on MgO(001) substrates by using nanoindentation. The lattice parameters and residual strain/stress of TiNxOy films decrease as oxygen concentration increases. Hardness and Youngʹs modulus determined by nanoindentation are about 17–26 GPa and 355–430 GPa, respectively, which vary with chemical composition and residual stress.
