P. Vaija et al., APPLICATION OF METHODS OF FUZZY MATHEMATICS TO THE DETERMINATION OF THE MICROMORPHOLOGY OF TIO2 CVD THIN-FILMS, Journal of the European Ceramic Society, 11(6), 1993, pp. 551-557
The influence of the process parameters (temperature, total pressure,
partial pressure of the TiO2 precursor) has been studied. A columnar m
orphology is obtained above 500-degrees-C at low pressure, while equia
xial crystals are observed at high total pressure. The experimental mo
rphology diagram derived from the experimental observations was comple
ted applying a simple fuzzy expert system and a fuzzy extrapolation me
thod.
