  • 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...

  • New chemistry for electrochemical energy storage applications

    Creator:
    Wang, Xingfeng
    Abstract:
    Electrochemical capacitors and batteries are two major electrochemical energy storage technologies, which have been investigated extensively to meet the rapidly-growing demand for higher energy, higher power, lower cost and enhanced safety in the past few decades. With the charge storage mechanism of electrostatic charge adsorption desorption via electrical double layers,...

  • Tuning Functional Properties of Pyrochlore and Related Oxides via Cation and Anion Substitutions

    Creator:
    Giampaoli, Gabriella C. S.
    Abstract:
    Inorganic structures play an important role in materials due to their versatility and diversity. A complete understanding of the structure of a material is vital to enhance the creation of new materials that fill voids in research. The rational design of these compounds is driven by the exploitation of structure-property...

  • Fundamental Studies of the Structure-Property Correlations of Na-ion and K-ion Storage in Non-Graphitic Carbon

    Creator:
    Li, Zhifei
    Abstract:
    Grid-scale energy storage systems are urgently needed to increase the flexibility and rigidity of the grid for modern society and take full advantage of the renewable green energy resources such as solar energy and wind energy. Na-ion batteries (NIBs) and K-ion batteries (KIBs) have been emerged as one of the...

  • Characterization and Investigations of Thin-Film Materials with X-ray Photoelectron Spectroscopy

    Creator:
    Diulus, J. Trey
    Abstract:
    Surface characterization of materials is widely utilized over a range of disciplines and essential to the development of new materials, technology, or processes. Metal oxide nanoclusters have shown promise as potential new generation photoresist materials for extreme ultraviolet (EUV) nanolithography. Organotin clusters have been proposed as potential candidates for resist...

  • Transition Metal Oxides for Aqueous Electrochemical Energy Storage

    Creator:
    Jiang, Heng
    Abstract:
    In the 21st century, environmental deterioration is now an indisputable fact. Reliable and economically viable electricity systems based on renewable sources are urgently needed to replace the environmentally detrimental fossil fuels. The feasibility of incorporating renewable-but-intermittent solar and wind energy heavily depends on the development of cost-effective and safe technologies,...

  • Venturing Beyond Crystallinity and Into Amorphous Space : A Na-ion Battery Perspective

    Creator:
    Bommier, Clement
    Abstract:
    As scientists, we have an affinity for order: repeating crystal structures, Euclidean space, continuous functions… Even concepts such as defects are discussed in the context of distracting from order. Things are most logical and best described in straightforward, taxonomical fashion. But what happens when the very application desired is dependent...
