Abstract :
Fe-based cadmium sulfide alloy thin films have been grown on c -plane sapphire substrates by a low-pressure metalorganic chemical vapor deposition technique at different growth temperatures. From X-ray diffraction and absorption spectra of the samples, the evolutions with growth temperature show an inflexion at the growth temperature of 300 ∘C. This was attributed to the phase transformation from zinc-blende to wurtzite. With increasing growth temperature from 270 ∘C to 360 ∘C, Fe concentration in the films increases monotonously. The electronic states of Cd1−xFexS were investigated by X-ray photoelectron spectroscopy. Magnetic measurement shows Van Vleck paramagnetism of the Cd1−xFexS thin film in the temperature region below 7 K.
