    Foley, Brian M., Brown-Shaklee, Harlan J., Duda, John C., Cheaito, Ramez, Gibbons, Brady J., Medlin, Doug, Ihlefeld, Jon F., and Hopkins, Patrick E.
    Abstract:
    We measure the thermal conductivities of nano-grained strontium titanate (ng-SrTiO₃) films deposited on sapphire substrates via time-domain thermoreflectance. The 170 nm thick oxide films of varying grain-size were prepared from a chemical solution deposition process. We find that the thermal conductivity of ng-SrTiO₃ decreases with decreasing average grain size and attribute...

  • Studies of Structurally Complex Thin Film Oxides for Electronic Materials

    Creator:
    Fast, Dylan Braucht
    Abstract:
    In this dissertation, the structure and electronic properties of multiple metal oxide thin films are characterized and presented. Prompt inorganic condensation (PIC) of metal-oxo and –hydroxo clusters was evaluated as a technique for making metal oxide clusters in two separate studies. The first focuses on the synthesis of lithium niobate...

  • Thermal conductivity measurements of amorphous thin films on silicon via the 3ω method

    Creator:
    Wiedle, River Alan
    Abstract:
    Thermal transport properties of a material are often difficult to measure, especially for thin films, but they are important for materials that have applications in modern devices, such as nano-scale electronics, thermoelectrics, and thermally resistive coatings. In this thesis, we describe an apparatus developed to measure the thermal conductivity of...

  • Thermally-stable amorphous metal thin films

    Creator:
    McGlone, John M.
    Abstract:
    Amorphous metal thin films (AMTFs) are of potential use for metal-insulator-metal (MIM) tunnel diode applications due to their ultra-smooth surfaces, a consequence of their amorphous microstructure. The objective of this thesis is to design a thermally-stable AMTF capable of maintaining MIM tunnel diode performance after a post-deposition anneal in excess...

  • Applications of the thermal wave technique in liquid thermal conductivity measurements and flow field diagnostics

    Creator:
    Wang, Zhefu
    Abstract:
    The thermal wave technique has been explored for the use of liquid thermal conductivity measurement and flow property diagnostics in this dissertation. For liquid thermal conductivity measurements, an experimental technique based on the thermal wave approach is developed. A stainless steel strip functions as both a heating element and a...

  • Growth, characterizations and applications of copper sulfide thin films by solution-based processes

    Creator:
    Vas-Umnuay, Paravee
    Abstract:
    Copper sulfides (Cu[subscript x]S) are compound semiconductor materials that exhibit considerable optical and electrical properties varying significantly as a function of the composition. Copper sulfide thin films can be used in many applications, such as solar control coatings, solar cells, photothermal conversion of solar energy, electroconductive coatings, and microwave shielding...

  • The chemistry and device applications of amorphous thin-film interfaces

    Creator:
    Knutson, Christopher C.
    Abstract:
    Solid-state amorphous materials show amazing promise in thin-film electronics. The interface-to-bulk ratio of thin films makes interfacial chemistries of these systems of utmost importance. Thin films of amorphous metals, dielectrics and semiconductors have novel chemistries that are not only based upon their elemental constituent makeup, but also based upon the...

  • Development of Amorphous Metal Thin Films for Thermal Inkjet Printing and Microelectronics

    Creator:
    McGlone, John M.
    Abstract:
    Due to a lack of grain boundaries, an amorphous metal thin film (AMTF) possesses advantageous mechanical properties and enhanced chemical stability that is potentially useful for thermal inkjet (TIJ) printing applications. The use of an AMTF as a TIJ resistor or cavitation plate could lead to a thinner TIJ cavitation...

    Nagarajan, R., Draeseke, A. D., Sleight, A. W., and Tate, Janet
    Abstract:
    CuCr₁₋ₓMgₓO₂, a wide band gap semiconductor with the delafossite structure, has been synthesized in bulk and thin-film form. Bulk undoped CuCrO₂ is almost black and has moderate conductivity with p-type carriers. Upon doping with 5% Mg, the conductivity increases by a factor of 1000. In films, the best p-type conductivity...
