| Abstract | Growth and characterization of compositionally tuned, ytterbium-doped mixed lutetium-scandium oxide, and pure lutetia and scandia crystalline films are presented. Pulsed laser deposition was employed to grow these sesquioxide films, of thicknesses up to 20 µm, on (0001)-sapphire substrates. Varying the atomic ratio of lutetium to scandium in the target, the lattice parameter of the resulting films could be tuned to match that of the single-crystal c-cut sapphire substrate to achieve a lattice mismatch of <0.1%. Optimization of growth parameters led to a reduction of undesirable particulates and scattering points within the film. X-ray diffraction measurements show (222) orientated epitaxial growth with crystallinity comparable to bulk crystals. Through pole figure and electron-backscatter imaging measurements, it was found that two inverted cubic lattice orientations grow with micron-scaled domains. Growth of these lattice- matched mixed sesquioxides paves the way for high quality waveguides for generation of ultrashort laser pulses. |
