Abstract

The isothermal growth kinetics of sol-gel derived BaTi5O11 thin films has been studied by laser Raman spectroscopy. Thin films of the precursors were spin coated on silicon wafers with platinum or gold overlayers. The films were then annealed isothermally, and Raman spectra were recorded in situ. The time-dependent intensity changes of the Raman bands could be analyzed in terms of Avrami models. The interaction of the BaTi5O11 film with the platinum or gold overlayers during heat treatment apparently increased the Raman intensity by a factor of about 100.
