  • 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...

  • New multi-functional chalcogenides for photovoltaic and thermoelectric materials

    Creator:
    Heo, Jaeseok
    Abstract:
    The subject of this PhD thesis is part of a research domain of great present interest in new semiconductor materials for photovoltaic and thermoelectric applications. This domain contains the elaboration and the study of both Cu-based chalcogenides bulk and thin-film samples, driven by materials design principles. One of the most...

  • 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...

  • Chemistry of High-Resolution Organotin Patterning Materials

    Creator:
    Kenane, Nizan
    Abstract:
    Organotin clusters have attracted notable attention for use as inorganic photoresists. This dissertation discerns dimeric and dodecameric organotin clusters, [(n-C₄H₉Sn)(OH)(H₂O)Cl₂]₂ (Sn₂) and [(n-C₄H₉Sn)₁₂O₁₄ (OH)₆ ]+ (Sn₁₂), both of which are stable hydrolysis and condensation products of n-C₄H₉SnCl₃. This work identifies Sn₂ as a superior precursor choice for solution deposition of...
