  • Fabrication and characterization of nanostructured surfaces for enhanced heat transfer

    Creator:
    Choi, Changho
    Abstract:
    This objective of this study is to investigate the capability of nanostructured surfaces on dissipating heat flux by performing pool boiling and convective flow boiling. The generation of ultra-high heat flux from high performance electric devices has motivated a number of investigations related to advanced heat transfer especially in two-phase...

  • 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...

  • Growth, Characterization and Applications of Zinc Sulfide Thin Films by Solution-Based Processes

    Creator:
    Chiu, Dick
    Abstract:
    Zinc Sulfide (ZnS) thin film, with a wide band gap, has been used for many applications, such as buffer layer for CIGS solar cells, light emitting diodes and thin film electroluminescent devices. In this work, ZnS thin films were prepared using two different deposition processes. In the first method, ZnS...

  • CdS nanocrystalline thin films deposited by the continuous microreactor-assisted solution deposition (MASD) process : growth mechanisms and film characterizations

    Creator:
    Su, Yu-Wei
    Abstract:
    The continuous microreactor-assisted solution deposition (MASD) process was used for the deposition of CdS thin films on fluorine-doped tin oxide (FTO) glass. The MASD system, including a T-junction micromixer and a microchannel heat exchanger is capable of isolating the homogeneous particle precipitation from the heterogeneous surface reaction. The results show...

  • Formation of Cu₂ZnSnS₄ Thin Films via Reactive Sintering of Binary Metal-Sulfide Nanoparticles Using Intense Pulsed Light

    Creator:
    Zeng, Cheng
    Abstract:
    Copper zinc tin sulfide (CZTS) is a potential solar material for thin film solar cells according to its suitable band gap in the visible light range, high absorption coefficient, low toxicity, good photostability and relative earth abundance of component elements. However, the production cost of this solar thin film material...

  • 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...

    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....
