Surface oxidation of Cu(100) has been investigated by variable temperature scanning tunneling microscopy and quantitative x-ray photoelectron spectroscopy as a function of O2 pressure (8.0×10−7 and 3.7×10−2mbar) at 373K. Three distinct phases in the initial oxidation of Cu(100) have been observed: (1) the formation of the mixed oxygen chemisorption layer consisting of Cu(100)-c(2×2)-O and Cu(100)-(22×2)R45°-O domains, (2) the growth of well-ordered (22×2)R45°-O islands, and (3) the onset of subsurface oxide formation leading to the growth of disordered Cu2O. We demonstrate that the (22×2)R45°-O reconstruction is relatively inert in the low pressure regime. The nucleation and growth of well-ordered two-dimensional Cu–O islands between two (22×2)R45°-O domains is revealed by time-resolved scanning tunneling microscopy experiments up to 0.5 ML of oxygen. The formation of these islands and their nanostructure appear to be critical to the onset of further migration of oxygen atoms deeper into copper and subsequent Cu2O formation in the high pressure regime. The reactivity of each phase is correlated with the surface morphology and the role of the various island structures in the oxide growth is discussed.

“…In previous studies, the electrical properties and photoelectrical ones of the oxide film on a glass and Cu sheet have been reported. [5][6][7][8] However, the relationship between photopotential and durability of the oxide film is not apparent. In addition, there are few works to report the effect of a substrate on the property of the electrode.…”

“…It is important to know that the preparation technique can define the electrical and optical properties of the films [4]. Various methods such as evaporation [5][6][7], chemical vapor deposition [8], sputtering [9][10][11][12][13], thermal oxidation [14], sol-gel process [15], were used to produce the copper oxide film. The advantages of sputtering method are its flexibility, scalability, complexity of possible films, reproducibility, ability to work at low temperature, capability to deposit precisely controlled hetero structures, and simplicity of controlling the film composition, structure and morphology.…”

In this study, the effect of oxygen content on a thin copper oxide layer deposited on BK7 and steel substrates by DC magnetron sputtering were investigated. Argon as working gas with impurity of 99.9% and various oxygen ratios were used to sputter a pure Cu cathode target in a cylindrical geometry. The produced samples were analyzed by X-ray diffraction (XRD), energy-dispersive X-ray (EDX), atomic force microscopy (AFM), and spectrophotometry techniques. The films thickness was measured by profilometer facility. The results show that by increasing oxygen content in the working gas the sputtering rate reduces. Moreover, the type of oxide phase (Cu 2 O or CuO) in the synthesized layer and consequently its optical properties dramatically depend on Ar/O 2 ratio in the working gas.
