  • Synthesis and catalytic applications of derivatives of 7,7'-dihydroxy-8,8'-biquinolyl (azaBINOL)

    Creator:
    Wang, Chao
    Abstract:
    The synthesis of axially chiral polyfunctional derivatives of 8,8'-biquinolyl was explored and the catalytic action of appropriate derivative types investigated in three separate processes: (1) the silylcyanation of carbonyl groups and imines, (2) alkylation of a glycine Schiff-base via phase transfer-catalysis, and (3) direct amide bond formation from simple amines...

  • 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...

  • Computational and experimental investigation of steady flow fields, turbulence, and hemodynamic wall stresses in patient-specific abdominal aortic aneurysm models

    Creator:
    Edgar, Erik S.
    Abstract:
    Steady flow fields and flow-induced wall stresses have been evaluated by experimental measurements and computational fluid dynamics (CFD) analysis in a series of patient-specific abdominal aortic aneurysm (AAA) models, over a range of Reynolds numbers (Re) from 125 to 3000 (500 to 3000 for CFD). Experimental methods used particle image...

  • Terahertz Imaging and Nonlinear Spectroscopy of Semiconductors using Plasmonic Devices

    Creator:
    Thompson, Zachary James
    Abstract:
    In this dissertation, a series of studies in the field of terahertz (THz) science are presented, specifically using nonlinear THz spectroscopy. We exploit huge field enhancement and subwavelength confinement in plasmonic structures. There are three distinct projects which will be discussed: nonlinear THz spectroscopy using plasmonic induced transparency (PIT), THz-triggered...

  • BaCuChF (Ch = S, Se, Te) p-type transparent conductors

    Creator:
    Zakutayev, Andriy
    Abstract:
    BaCuChF (Ch = S, Se, Te) materials are chalcogen-based transparent conductors with wide optical band gaps (2.9 – 3.5 eV) and a high concentration of free holes (10¹⁸ – 10²⁰ cm⁻³) caused by the presence of copper vacancies. Chalcogen vacancies compensate copper vacancies in these materials, setting the Fermi level...

  • Theoretical study of beryllium borohydride Be(BH₄)₂

    Creator:
    Alghamdi, Maha D.
    Abstract:
    Ab initio calculations using the B3LYP and CCSD(T) methods were employed in this work to explore the most stable structure of the intriguing compound Be(BH₄)₂, for which as many as seven different structures have been proposed in the literature. Use of the B3LYP density functional method with several large basis...

  • Thermal conductivity measurements of amorphous metal thin films via the 3ω method

    Creator:
    Zhan, Kai
    Abstract:
    Amorphous multicomponent metals have promising applications in novel electronic devices because of their atomically smooth surface morphology and lack of grain boundaries. It is important to understand the thermal transport properties of amorphous metals and an accurate measurement of their thermal conductivity will be essential for further improvement of device...

  • Electrical recommendations and formulas for metal fill in radio-frequency integrated circuits

    Creator:
    Gaskill, Steven
    Abstract:
    With increasing transistor operating frequencies, interconnects and passive devices are becoming performance limiters in integrated circuit (IC) designs. To combat this, the interconnect layers above the active silicon are trending toward low-κ dielectrics and Cu metallization. The use of these new materials has popularized chemical mechanical polishing (CMP) to planarize...

  • Much Ado About Weak Measurement

    Creator:
    Bauml, Benjamin Noë
    Abstract:
    I had to write again. My research lay in science, and it was a science of three parts. The first part made a careful, introductory chapter, begged for by things that were lacking. It summarizes the von Neumann measurement model, derived from the Stern-Gerlach experiment, and it explains how weak...
