  • Development of oxide semiconductors : materials, devices, and integration

    Creator:
    Chiang, Hai Q.
    Abstract:
    The aim of this dissertation is to develop oxide semiconductors by radio-frequency sputtering for thin-film transistor (TFT) applications. A variety of oxide semiconductors are used as the TFT channel layer, including indium gallium oxide (IGO), zinc tin oxide (ZTO), and indium gallium zinc oxide (IGZO). The variety of materials used...

  • Wide band gap semiconductors and insulators : synthesis, processing and characterization

    Creator:
    Hersh, Peter A.
    Abstract:
    The work presented here is focused on applying basic principles of solid-state chemistry to the study and development of new wide band-gap semiconductors and insulators for photovoltaic and electronic-device applications. Analysis of crystal structure, band structure, optical band gap, morphology and transport properties provides fundamental insight into materials performance as...

  • Synthesis and function of bioactive, block copolymer surfactant constructs as relevant to the preparation of anticoagulant and antibacterial medical implant surfaces.

    Creator:
    Joshi, Pranav R.
    Abstract:
    Nisin, an antibacterial peptide proven to be an effective inhibitor of Gram-positive bacteria, was incorporated into novel block copolymer constructs and tested for retained antibacterial activity. Covalent coupling was achieved by chemical modification of the N-terminal isoleucine to introduce a thiol group. Thiolated nisin derivatives were then linked to poly[ethylene...

  • Metallic nanoscale conductors

    Creator:
    Nebergall, Nathan Sky
    Abstract:
    A new, reproducible method of using electromigration to form metallic nano-conductors is developed using gold and a tin-silver alloy. Measurements revealed a quantization of the electrical conductance consistent with the theory of quantum conductance. The theory of quantum conductance is applied to show that a nano-conductor with a cross-section of...

  • Design, fabrication and application of a microfluidic nanofiltration module for separation and purification of macromolecules and nanoparticles

    Creator:
    Rundel, Jack T.
    Abstract:
    A microfluidic nanofiltration module has been designed, fabricated and applied to the continuous-flow, pressure-driven, post-synthetic purification of macromolecules and nanoparticles via diafiltration using a commercially available organic solvent resistant nanofiltration membrane, STARMEM 122. This module will readily interface with other microscale components within a "nanofactory" for the rapid synthesis, purification...

  • High quantum-yield phosphors via quantum splitting and upconversion

    Creator:
    Jeong, Joayoung
    Abstract:
    The Gd3+ ion has been used to induce quantum splitting in luminescent materials by using cross-relaxation energy transfer (CRET). In Nd:LiGdF4, quantum splitting results from a two-step CRET between Gd3+ and Nd3+, first involving a transition 6G→6I on Gd3+ and an excitation within the 4f3 configuration of Nd3+ followed by...
