Epitaxial growth of cadmium films by the hot-wall technique

X-ray diffraction study of epitaxial zinc and cadmium films prepared by hot-wall technique

“…The conventional method of vacuum deposition of cadmium films does not give good quality homogeneous films deposited on glass substrate (Bandopadhyay and Pal 1979). We have already shown that, by using the hot-wall technique, good quality cadmium films consisting of large crystal domains with only [002] orientation, can be obtained (Kulkarni et al 1984). The present paper reports the effect of elevated substrate temperature on the epitaxial growth of zinc as well as cadmium films.…”

“…The apparatus used to deposit cadmium and zinc films was essentially the same as described earlier (Kulkarni et al 1984). The only modification was to replace corning glass tube with quartz tube having larger dimensions (height 6.0cm; outer dia.…”

“…The growth process is strongly influenced by the temperature as well as the nature of the substrate. Cadmium films deposited on NaC1 (t00) single crystal substrate show preferred orientations in [101], [102], [103] and [002] directions in decreasing order (Kulkarni et al 1984). The polycrystalline nature of the films deposited on this substrate is due to the lattice mismatch and relative positioning of cadmium atoms (Chopra 1969).…”
