  • Low-temperature, Inkjet-printed p-Type Copper(I) Iodide-based Thin-Film Transistors

    Creator:
    Gorecki, Jenna Y.
    Abstract:
    Inkjet-printed p-type copper(I) iodide-based TFTs were successfully fabricated. As-printed copper(I) halide semiconductor films, such as CuI, CuBrI, and CuClI, were used as p-type active channel layers for TFTs. The entire process of the TFTs fabrication was maintained under 150 °C, which is compatible with flexible plastic substrates and transparent glass...

  • Fabrication of CuInGaSe₂ thin film solar cells using low-cost air-stable inks

    Creator:
    Wang, Wei
    Abstract:
    CuInGaSe₂ (CIGS), a promising thin film solar cell material, has gained lots of attention in decades due to its high energy conversion efficiency and potential lower manufacture cost over conventional Si solar cells. As a cheaper processing method compared to vacuum-based techniques, solution-based deposition has been successfully applied to fabricate...

  • Development of solution-based reaction processes for micro- and nano-structured semiconductors

    Creator:
    Lee, Doo-Hyoung
    Abstract:
    The focus of this study is to develop a general and low-cost solution-based process to fabricate micro- and nano-structured semiconductors that are suitable for electronics. This process uses simple metal halide precursors dissolved in a solvent (organic or aqueous) and is capable of forming uniform and continuous thin films via...

  • Growth, Characterizations, and Applications of Patterned Nanostructured Thin Film

    Creator:
    Gao, Zhongwei
    Abstract:
    A unique microreactor-assisted nanomaterial synthesis and printing process was studied for the fabrication of patterned metal oxide nanostructured thin films. The process uses a continuous flow microreactor to control and generate a reactive chemical flux that was transported to a patterned microfluidic channel. The microreactor-assisted nanomaterial synthesis process can generate...

  • Investigation of solution-based processes for functional metal oxides : printing, nanostructures, and applications

    Creator:
    Han, Seung-Yeol
    Abstract:
    The various solution-based processes, spin coating, inkjet printing, microreactor assisted nanoparticle deposition (MANDTM) and spin-successive ionic layer absorption and reaction (Spin-SILAR) were used to demonstrate thin film electronics and anti-reflective coatings. Several aspects of thin film transistors (TFTs) were tested including a range of temperatures, annealing atmosphere, and deposition methods....

    Creator:
    Hu, Jiqing
    Abstract:
    Ferrites have been used for various high frequency applications as bulk materials. These applications, however, are limited to large dimension devices. In this thesis, thin film ferrites were deposited from a low temperature solution-based deposition process that is suitable for micro-scale high frequency applications. The low temperature nature of this...
