  • 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...

  • 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...

  • 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...
