摘要
Thin films Of Co3O4 have been successfully deposited on SiO2/Si(100) and MgO(001) substrates by atomic layer deposition (ALD) using the precursor combination CoI2/O-2. The deposition temperature was found to have a strong influence on the growth rate. On SiO2/Si(100) substrates, growth rates of about 0.2 nm per cycle were recorded at 500 degrees C, decreasing to 0.004 nm per cycle at 700 degrees C. Oil MgO(001) substrates the growth rates were lower, reaching about 0.12 nm per cycle at 475 degrees C, while no growth could be detected at 700 degrees C. The films were found to grow as the cubic Co3O4 phase throughout the temperature range 475-700 degrees C, polycrystalline on SiO2/Si(100), and epitaxial on MgO(001). On MgO(001) the epitaxial relationship was established to the in-plane orientation (001)[100](Co3O4)parallel to(001)[100](MgO). No iodine could be detected by Rutherford backscattering spectroscopy (RBS) or by X-ray fluorescence (XRF) spectroscopy in any of the deposited films.
