Abstract

Thermally and ion-induced reactions of transition metals Zr, Ti, Cr and Ag with CuO substrates have been studied by Rutherford backscattering spectrometry and X-ray diffraction techniques. Reactions resulted in the configuration of ZrO2/Cu2O/CuO from Zr/CuO structure and TiOx/Cu2O from Ti/CuO structure after thermal annealing and ion irradiation. No significant reaction has been found in Cr/CuO after vacuum annealing at 410°C and 300 Key Xe ions irradiation at 240°C. Ag atoms balled up on CuO surface after annealing at 610°C. A comparison of the reaction layers has been made in both metal/SiO2 and metal/CuO systems after thermal annealing and ion irradiation. Both heats of reaction and bond strength in the substrates can influence the chemical reactivity between metal layer and substrate.
