|Title:||Influence Of The Substrate On The Crystalline Properties Of Sprayed Tin Dioxide Thin Films|
|Abstract:||Undoped tin dioxide films were produced by the conventional spraying method over five different substrates: commercial glass, fused quartz, monocrystalline Si, 7059 Corning glass and amorphous Si at different substrate temperatures (Ts). For each kind of substrate, the temperature range in which the films became polycrystalline was determined using X-ray diffractometry. The amorphous to polycrystalline transition temperature (Tap) was found to vary with the type of substrate used. From these results we concluded that for sprayed SnO2 films the crystallinity of the films depends not only on the deposition temperature but also on the nature of the substrate. Preferential orientation in the  direction was noted for all the films deposited at Ts < 490°C regardless of substrate nature and temperature. © 1986.|
