  • 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...

  • Label free biosensing with carbon nanotube transistors

    Creator:
    Leyden, Matthew R.
    Abstract:
    As electronics reach nanometer size scales, new avenues of integrating biology and electronics become available. For example, nanoscale field-effect transistors have been integrated with single neurons to detect neural activity. Researchers have also used nanoscale materials to build electronic ears and noses. Another exciting development is the use of nanoscale...

  • Fabrication and optical measurement of flip-chips for noninvasive electrostatic gating of nanomaterials

    Creator:
    Nichols, Dublin MacCray
    Abstract:
    Electrostatic gating of nanomaterials allows researchers to control carrier density and shape potential barriers that confine carriers. Lithographic patterning followed by metal deposition is the standard technique to define electrostatic gates; however, the methods of fabricating these devices often involve harsh processing. For example, taking a material to high temperatures...

  • Functional Materials and Techniques for Additive Manufacturing in Soft Robotics

    Creator:
    Walker, Stephanie
    Abstract:
    This thesis outlines the development of new elastomeric materials and manufacturing processes for soft robotics. Specifically, this work describes the development of custom material formulations for use in additive manufacturing, additive manufacturing processing techniques for silicone elastomers, and multi-component additive manufacturing techniques. Material synthesis and processing is a gap in...

  • Scanning photocurrent microscopy study of photovoltaic and thermoelectric effects in individual single-walled carbon nanotubes

    Creator:
    DeBorde, Tristan
    Abstract:
    Carbon Nanotubes are a unique family of nanostructures that have shown remarkable promise for mechanical, electrical, and optical applications. Fundamentally similar to the earlier discovered Buckminsterfullerene (C₆₀), carbon nanotubes are hollow cylinders formed from a single sheet of carbon atoms. The research presented in this dissertation investigates several carbon nanotube...
