  • A new trigonal huntite material and subgroup relationships between crystallographic space groups

    Creator:
    Hruschka, Michael Archimedes and Hruschka, Michael A.
    Abstract:
    The use of an adjacency matrix to determine distant (not maximal or minimal) subgroup and supergroup relationships between crystallographic spacegroup types is described. Full lists of space-group types that are supergroups and subgroups for every space-group type were compiled. A list of the space-group types connected to each space-group type...

  • New luminescent materials and high-performance solution-processed oxide thin films

    Creator:
    Jiang, Kai
    Abstract:
    Crystals of an incongruent-melting compound, Ba₃MgSi₂O₈, were grown by the flux method and its structure was determined by single crystal X-ray diffraction methods. Ba₃MgSi₂O₈ crystallizes in trigonal space group P-3[bar]m1 with a = 5.6123(3) Å, c = 7.2667(9) Å and Z = 1. Eu²⁺ ions prefer one crystallographic Ba site...

  • Thin-Film Dielectric Structure of Spin-Coated ZrO2 from Aqueous Inorganic Solution

    Creator:
    Moreno Luna, Hidekel A.
    Abstract:
    An inorganic aqueous precursor for the deposition of ZrO2 thin films via spincoating was developed. Hydrolysis and condensation chemistries of ZrOCl₂·8H₂O were used as the principal reactions to guide the synthesis. Refractive index, n, for a film annealed at 300 °C at 550 nm was measured to be n=1.97 by...

  • Copper and iron chalcogenides for efficient solar absorption

    Creator:
    Platt, Heather A. S.
    Abstract:
    This dissertation outlines two approaches for improving the efficiency and reducing the cost of photovoltaic energy generation. First, the structures of known binary copper and iron compounds are used to choose the promising compositions Fe₂XS₄ (X = Si, Ge), Cu₃TaQ₄ (Q = Se, Te), and BaCuQ'F (Q' = S, Se,...

  • Aqueous chemistries for oxide electronics

    Creator:
    Meyers, Stephen T.
    Abstract:
    The variegated aqueous chemistries of metal cations are applied to the design and synthesis of non-toxic solution precursors suitable for additive printing of large-area oxide electronics. Polycondensation behaviors of aqueous Al+3 and PO4 +3 are manipulated in the deposition of atomically smooth amorphous aluminum oxide phosphate (AlPO) dielectric films. AlPO...

  • Solution deposition and characterization of the thin film inorganic materials

    Creator:
    Özmen, Bahar
    Abstract:
    The general emphasis of this work has been synthesis, characterization, and applications of n- and p-type inorganic oxide thin films that are deposited from solutions. In particular, a study of n-type transparent semiconductor films of tin (IV) oxide and zinc-doped tin (IV) oxide has been performed by spin coating. Solution...

  • Metal-oxo Clusters as Novel Photolithographic Materials: How Understanding the Chemistry of HafSOx Informs Next-Generation Patterning Systems

    Creator:
    Amador, Jenn M.
    Abstract:
    The solution chemistry and kinetic behavior of hafnium peroxy sulfate solutions ("HafSOx") is described in terms of peroxide content and solution speciation. Additionally, thin film behavior, including thermal behavior and solubility, is characterized, and a mechanism of patterning is presented, as well as parameters that should be considered when looking...

    Creator:
    Telecky, Alan J.
    Abstract:
    The chemistry of hafnium oxide based and materials are described in the context of ion exchange and lithography. HafSOx, represented by the composition HfO₂₋[subscript x](SO₄)x, is described to possess a significant capacity towards ion exchange in acidic and basic solutions, enabling films of HafSOx to be cleanly and readily be...

  • Deposition and characterization of transition metal oxides from aqueous solution

    Creator:
    Betterton, Sharon A.
    Abstract:
    The aqueous chemistries of two transition metal cations, Zr⁴⁺ and Nb⁵⁺, are examined and then used to develop inorganic precursor solutions. The oxides of these cations (ZrO₂ and Nb₂O₅) are deposited and characterized, and their morphological and optical properties discussed. Due to the obstacles created by niobium's aqueous chemistry, an...
