Abstract
Various embodiments provide for systems and techniques for the successful fabrication of metal oxide (TMO)-on-glass layer stacks via direct deposition. The resulting samples feature epitaxial, strontium titanate (STO) or barium titanate (BTO) films on silicon dioxide (SiO) layers, forming STO- or BTO-buffered SiOpseudo-substrates. As the integration of TMO films on silicon rely on an STO or BTO buffer layer, a wide variety of TMO-based integrated devices (e.g., circuits, waveguides, etc.) can be fabricated from the TMO-on-glass platform of the present technology. Moreover, the STO, or the BTO, survives the fabrication process without a corresponding degradation of crystalline quality, as evidenced by various objective measures.
