  • Zinc tin oxide thin-film transistor circuits

    Creator:
    Heineck, Daniel Philip
    Abstract:
    The primary objective of this thesis is to develop a process for fabricating integrated circuits based on thin-film transistors (TFTs) using zinc tin oxide (ZTO) as the channel layer. ZTO, in contrast to indium- or gallium-based amorphous oxide semiconductors (AOS), is perceived to be a more commercially viable AOS choice...

  • Via-only microwave/millimeter wave bandpass filters for LTCC applications

    Creator:
    Bhargava, Gaurav
    Abstract:
    With an increasing number of wireless applications at microwave frequencies, the frequency spectrum is becoming quite crowded. Due to this congestion, the current state of technology is leading towards upper microwave and millimeter wave spectra as they also offer other distinct advantages such as larger bandwidth and smaller component footprint....

  • Ultra-Wideband receiver implementation using analog correlators

    Creator:
    Harbert, Kyle
    Abstract:
    This paper proposes a novel means of using analog correlators to improve upon existing Ultra-Wideband receiver architectures. Current architectures aim for an all-digital design for the sake of ease of implementation and conceptual simplicity. This causes some notable design challenges including an ultra-high sampling rate, and difficulty capturing multipath energy....

  • Transition metal solar absorbers

    Creator:
    Altschul, Emmeline Beth
    Abstract:
    A new approach to the discovery of high absorbing semiconductors for solar cells was taken by working under a set of design principles and taking a systemic methodology. Three transition metal chalcogenides at varying states of development were evaluated within this framework. Iron pyrite (FeS₂) is well known to demonstrate...

  • Thin-film transistors with amorphous oxide channel layers

    Creator:
    Grover, Manan S.
    Abstract:
    In recent years, a new class of high-performance thin-film transistors (TFTs) has emerged comprising amorphous oxide channel materials composed of heavy-metal cations (HMCs) with (n-1)d¹⁰ns⁰ (n ≥ 4, where 'n' refers to the row of the periodic table) electronic configuration. This thesis is devoted to the fabrication and characterization of...

  • Synthesis of Plasmonic-Enhanced Metal-Organic Framework Thin Films and their Infrared Sensing Application

    Creator:
    Ma, Guoheng
    Abstract:
    Transparent and electrically conductive metal oxide nanoparticles have attracted much attention, and can be used to improve the performance of solar cells, transparent electrode materials, and gas sensor technology. Specifically, indium tin oxide (ITO) nanocrystals (NCs) are potentially useful nanomaterials, having technological applications in enhanced sensitivity of optical spectroscopy due...

  • Solution-based deposition of functional thin films : development of a glucose biosensor and thermal processing of CZTS nanoparticle films

    Creator:
    Durgan, Christopher J.
    Abstract:
    The development of solution-based methods for deposition of different thin film material is presented as an alternative to high cost vacuum-based methods. For certain materials, vacuum techniques are unsuitable for processing. Additionally, vacuum-based processes present high capital costs associated with equipment, and slow processing times. Atmospheric pressure solution based techniques...

  • Solution-based Chalcogenide Thin Film Deposition

    Creator:
    Pan, Changqing
    Abstract:
    As a group of promising semiconductor materials, metal chalcogenides in thin film form have been widely used in electronics and optoelectronics applications, such as solar cell devices and photon sensors. Unfortunately, the film size and product throughput are limited by the current vacuum-based thin film deposition techniques. Solution-based thin film...

  • Printing 3D Magnetic Composite Structures with Arbitrary Anisotropy using UV-curable Magnetic Ink

    Creator:
    Clay, Garrett
    Abstract:
    Inkjet printing offers a cost effective, highly customizable method for rapid manufacturing of functional devices with minimal material waste. Although this method has been used for a variety of composites, little work has been done in the area of 3D printing magnetic composites. Presented here is a process for inkjet...
