New method for growing barium titanate films at atmospheric pressure

September 27, 2005

Many advanced material fabrication techniques use multi-step processes that can be environmentally stressing, energy-consuming and have high-costs.

In an article published in AZojomo* researchers have described a novel method called "Localized Hydrothermal Technique" for growing coatings of barium titanate or other complex oxides on titanium. In this method, thin films grow on transition metal substrates by Joule heating of the substrate while it is immersed in an aqueous alkali-earth hydroxide solution, thus locally obtaining hydrothermal conditions. The films exhibited the characteristic structure of deposits grown in solution under standard hydrothermal conditions.

This technique uses an extremely simple and low energy consumption experimental setup that has not been previously reported for the fabrication of perovskite thin films.
