  • Origin of p-type conduction in single-crystal CuAlO₂

    Creator:
    Tate, Janet, Ju, H. L., Moon, J. C., Zakutayev, A., Richard, A. P., Russell, J., and McIntyre, D. H.
    Abstract:
    We report measurements of the structural, optical, transport, and magnetic properties of single crystals of the anisotropic p-type transparent semiconductor CuAlO₂. The indirect and direct band gaps are 2.97 and 3.47 eV, respectively. Temperature-dependent Hall measurements yield a positive Hall coefficient in the measured range and an activated carrier temperature...

  • p-type transparent electronics

    Creator:
    Valencia, Melinda Marie
    Abstract:
    The objective of this thesis is to contribute to the development of p-type materials for transparent electronics applications. Thin films of ®-BaCu2S2, a p-type semi-transparent semiconductor, are fabricated and characterized. ®-BaCu2S2 has a transmittance of 60% to 80 % in the visible portion of the electromagnetic spectrum. The mobility, conductivity,...

  • Analytical and numerical continuation methods for conductive temperature fields

    Creator:
    Eggers, Dwight Edward
    Abstract:
    The continuation of conductive temperature fields is being considered. The continuation of a field involves the extrapolation of a field known over a limited domain to an adjacent domain in such a way that it satisfies the heat conduction differential equation and other imposed constraints. Continuations forward in time and...

  • Submarine hydrothermal systems : a probable site for the origin of life

    Creator:
    Corliss, John B., Baross, John A., and Hoffman, Sarah E.
    Abstract:
    Submarine hydrothermal systems provide all of the conditions necessary for the abiotic synthesis of organic compounds, polymers, and simple cell-like organisms. An analysis of the Archaean rock and fossil record shows that fossils of simple organisms are found in rocks deposited in hydrothermal environments. Biochemical experiments have shown that thermal...

  • Single crystal growth, powder synthesis and characterization of layered chalcogenide semiconductors

    Creator:
    Richard, Annette Pauline
    Abstract:
    This thesis presents basic studies, including structural, optical and transport measurements, on novel chalcogenide powders and single crystals. BiCuOSe crystals have been synthesized for the first time. The crystal structure of BiCuOSe has been refined and the optical band gap has been measured to be 0.83eV. Crystal structure refinements of...

  • Heat conduction in eccentric annuli

    Creator:
    Ting, Yine-ping
    Abstract:
    Muitiregion annular geometry is a basic feature of energy removal systems ranging from advanced heat exchangers to fission reactor fuel rods. For the symmetric cases, the heat conduction through annular regions is well defined. However, for a shift of an annular region, analysis of the system must be made in...

    Creator:
    Zakutayev, Andriy
    Abstract:
    BaCuChF (Ch = S, Se, Te) materials are chalcogen-based transparent conductors with wide optical band gaps (2.9 – 3.5 eV) and a high concentration of free holes (10¹⁸ – 10²⁰ cm⁻³) caused by the presence of copper vacancies. Chalcogen vacancies compensate copper vacancies in these materials, setting the Fermi level...

  • Electronic Conduction Mechanisms in Insulators

    Creator:
    Chiang, Tsung-Han
    Abstract:
    The research presented herein focuses on electrical assessment of oxide thin films as insulators. The current density-electric field (J-E) characteristics of four insulators of dramatically different electrical quality are assessed in terms of their operative electronic conduction mechanisms. Conduction in the two high-quality insulators is dominated by Ohmic conduction and...
