  • In silico screening of nanoporous materials for gas sensing and separation

    Creator:
    Gantzler, Nickolas
    Abstract:
    The utility of high-throughput, computational screening has become an invaluable asset to the field of materials science. In the hierarchy of computational methods, the most accurate methods are often the most computationally expensive. However, as both the efficiency and fidelity of numerical techniques advance, high-quality screening of large materials datasets...

  • Bioelectronic Systems for Neurosensing Enabled by Graphene

    Creator:
    Fengel, Carly V.
    Abstract:
    Taking long-term electrical measurements of a large number of neurons simultaneously is required for many modern neuroscience experiments. However, such experiments are currently limited by the shortcomings of traditional neurosensing technology. For example, there is a significant mechanical mismatch between rigid silicon probes and soft biological tissues. This mismatch can...

  • Photostability of organic semiconductors : from bulk to nanoscales

    Creator:
    Quist, Nicole Arianne
    Abstract:
    Organic semiconductors have attracted considerable attention due to their applications in low-cost, solution-processable (opto)electronic devices. An important class of high-performance organic semiconductors is pentacene derivatives, which exhibit high charger carrier mobilities in field-effect transistors and ultrafast singlet fission in photovoltaic devices. These derivatives have served as benchmark materials for systematic...

  • Monte Carlo Radiation Transfer Simulations of Gamma Ray Burst Prompt Emission

    Creator:
    Parsotan, Tyler M.
    Abstract:
    Gamma Ray Bursts (GRBs) are the most energetic explosions in the Universe, producing up to $\sim10^{53}$ ergs of energy in the first few seconds of their emission -- the so-called prompt phase that is dominated by high energy X-ray and $\gamma$-ray photons. The very large luminosities released in these events...

  • Exciton and Polariton Nature in Organic Crystals

    Creator:
    Van Schenck, Jonathan D. B.
    Abstract:
    Understanding the impact of inter-molecular orientation on the optical proper-ties of organic semiconductors is important for designing next-generation organic (opto)electronic and photonic devices. However, fundamental aspects of how various features of molecular packing in crystalline systems determine the nature and dynamics of excitons have been a subject of debate. Toward...

  • Coordinatization Activated: How Students Understand and Apply Coordinate-Independent Integral Equations to Physics Situations

    Creator:
    Mulder, Gregory S.
    Abstract:
    Physics problems that require integration, such as finding the center of mass of an object or finding the electric field from a continuous distribution of charge, are one type of problem that is difficult for introductory physics students to solve. These problems require students to define a coordinate system in...

  • Electronic and Optical Properties of Defects in Amorphous Oxide and Transition Metal Dichalcogenide Semiconductors

    Creator:
    Vogt, Kyle
    Abstract:
    The optical and electronic properties of amorphous oxide thin films depend crucially on chemical composition, and deposition process variations which give rise to sub-gap defect states. Consequently, there is a need for a reliable, high-throughput method to extract sub-gap defect densities of states in amorphous oxide thin films. We present...

  • Exploring Student and Expert Understanding of Thermodynamic Potentials, Legendre Transformations, and Independent Variables in Thermodynamics

    Creator:
    Vignal, Michael
    Abstract:
    Thermodynamic potentials are energies that can describe a thermodynamic system in terms of different mathematically independent variables. Some of these potentials describe particular thermodynamic systems or processes in particularly convenient ways. In this dissertation, I discuss the different ways that students and experts reason about quantities in thermodynamics within the...

  • Synthesis and Analysis of Heterostructural Semiconductor Alloy Sn1-xCaxCh (Ch=S, Se) and Nitrides Zn1-xWxN and Zn1-x(W1-yMoy)xN

    Creator:
    Matthews, Bethany E.
    Abstract:
    This work explores the synthesis and characterization of the metastable alloys Sn1-xCaxCh (Ch= S, Se) and nitride compounds Zn-W-Mo-N, which have recently been predicted by theorists. Single phase thin films of Sn1-xCaxS are prepared by pulsed laser deposition and radio-frequency magnetron sputtering and of Sn1-xCaxSe are prepared by pulsed laser...

  • Heterojunction Assisted Impact Ionization at the ZnS/Si Interface and Cu_10Te_4S_13 Photodiodes

    Creator:
    Reidy, Christopher F.
    Abstract:
    Several topics are presented in this dissertation, each of which has applications to solar cells and photodetectors. First, we discuss the growth of Cu10Te4S13, copper tellurium tetrahedrite. This material has interesting optical properties; it has a large joint density of states at the conduction band maximum and valence band minimum,...
