  • Graphene Biotransistors, an Exploration of Neurosensing and Biofilm-sensing Applications

    Creator:
    Brown, Morgan A.
    Abstract:
    Atomically-thin graphene sheets have unprecedented characteristics for biosensing applications. These characteristics include mechanical flexibility and strength, optical transparency, electrical sensitivity and biocompatibility. The primary theme of this dissertation is the characterization and application of graphene field-effect transistors (FETs) in biologically-relevant physiological environments.Understanding the interface that forms between an electrolyte and...

  • Porous metal-organic materials for gas capture

    Creator:
    Rookard, Tanner Daniel
    Abstract:
    Metal-organic polyhedra (MOPs) are discrete molecules comprised of a metal and interconnecting ligands. The resulting MOP structures are porous cages, and to date, they have shown great promise toward gas capture. Ammonia is a hazardous gas that is produced in enormous quantities for use in fertilizers. In this talk, I...

  • Aqueous niobium chemistry at low pH : new precursors for oxide thin films

    Creator:
    Park, Deok-Hie
    Abstract:
    Phosphate and peroxide stabilize new oxo-hydroxo niobium clusters in water at low pH. The clusters open a new chapter in aqueous niobium chemistry under acidic conditions. The clusters also produce atomically smooth, amorphous niobium oxide phosphate (NbPOx) thin films. Reaction pathways from cluster solutions to amorphous niobium oxide phosphate solids...

  • Assessment of High Mobility Oxide Thin-Film Transistors

    Creator:
    Stewart, Kevin A.
    Abstract:
    The trend towards higher resolution, faster refresh rate active-matrix liquid-crystal displays (AMLCDs) as well as the emergence of active-matrix organic light-emitting diode (AMOLED) displays is driving the demand for amorphous oxide semiconductor thin-film transistors (AOS TFTs) with higher mobility. A physics-based model for carrier transport in an amorphous semiconductor is...

  • Polyoxoniobates: fundamental solubility trend and their application in solution and on the surface of thin films

    Creator:
    Rahman, Tasnim
    Abstract:
    Polyoxometalates (POMs) are anions consisting of three or more early transition metals ™ (Gr V and VI) oxoanions (in their highest oxidation state) linked together by a shared oxygen bond to form a 3D framework. Polyoxometalates (POMs) are a rapidly growing class of metal oxo clusters with a wide range...

  • Expediting the Generation and Analysis of Amorphous Oxide Computational Models: Modeling Complex Systems Swiftly

    Creator:
    Buchanan, Jacob C.
    Abstract:
    In this dissertation, the process of computational modeling of amorphous oxide materials is studied. Amorphous oxides have random atomic arrangements with no long-range structural order which makes it difficult to study structure-property relationships. Despite the difficulties, amorphous oxides have great uses as semiconductors and dielectrics in thin-film transistors. The ability...

  • Crystallization Rates of AIST and Ge Thin Films by Optical and Electron Microscopy

    Creator:
    Bird, Victoriea L.
    Abstract:
    The amorphous to crystalline phase change is of great interest for the production and operation of phase change memory and germanium electronic devices. Phase change memory relies on the ability to differentiate between differences in optical or electrical properties between the amorphous and crystalline phases of a single material. Amorphous...

  • Unique Structural Properties and Motifs of Metal-Oxides from Solids to Clusters

    Creator:
    Malmberg, Christopher E.
    Abstract:
    In this dissertation, the structural properties, thermodynamics and defect behavior of amorphous metal oxides and polyoxometalates are studied. Amorphous metal oxides have many applications, most notably as a semiconducting material used as the active matrix of thin film transistors. Alas, the amorphous nature of these materials makes studying them rather...
