Structural properties and IR-spectroscopy of Ni- and Fe-based heterogenous metal films

In this work a structural and functional study of as-deposited and annealed iron (Fe) and nickel (Ni) heterogenous thin films deposited by electron-beam evaporation is carried out. For structural analysis are used transmission electron microscopy (TEM) and selected-area electron diffraction (SAED). Fourier-transformed infra-red (FTIR) spectroscopy is used to analyze their compositional conditions and to measure their thickness using the novel technique (“fringing”-effect). TEM study has been shown that in both cases of obtained Fe and Ni films (as-grown and annealed) are observed the oxide phases which is confirmed by FTIR study. SAED study has been shown that in case of annealed Fe and Ni metal films are observed the halo which may be caused by the oxidation of obtained films.
