Use of sol-gels in the application of ceramic oxide thin films
… acid as a catalyst. In obtaining sols of niobia, tantala, and titania, increasing either the water content or the system concentration increased the rate of gelation. However, while a sufficient amount of nitric acid was required to promote the condensation of the metal oxide and inhibit the …

Coating Thermal Noise in Gravitational-Wave Detectors
… materials such as niobia-based oxides, hafnia-tantala mixtures, and substoichiometric silica, were explored employing strategies like compositional optimization, post-deposition annealing, and multimaterial designs with buried layers. Progress toward lower-noise coatings is demonstrated. Highly …

Phase equilibria, thermal expansion and symmetry relations within the HfO2-Ta2O5-TiO2-temperature system
Most material applications rely on a foundation of knowledge of phase equilibria. In this dissertation, a systematic approach to the rapid production of the high temperature HfO2-Ta2O5-TiO2 phase diagrams is presented that highlights the combined use of: (i) in-situ high temperature X-ray …
