  • Contact resistance and stability assessment of oxide-based thin film transistors

    Creator:
    Hung, Celia M.
    Abstract:
    This thesis focuses on two aspects of oxide-based thin-film transistors (TFTs), contact resistance and instability assessment. First, determination of the contact resistance of indium tin oxide (ITO) on two wide-band gap semiconductors, zinc oxide (ZnO) and indium gallium oxide (IGO), is attempted and the effects of contact resistance on device...

  • Thermally-stable amorphous metal thin films

    Creator:
    McGlone, John M.
    Abstract:
    Amorphous metal thin films (AMTFs) are of potential use for metal-insulator-metal (MIM) tunnel diode applications due to their ultra-smooth surfaces, a consequence of their amorphous microstructure. The objective of this thesis is to design a thermally-stable AMTF capable of maintaining MIM tunnel diode performance after a post-deposition anneal in excess...

    Abstract:
    The primary objective of this thesis is to explore new absorber and p-type window layer materials for thin-film solar cell applications. A new thin-film electron beam deposition system has been installed, is now operational, and has been used to deposit several types of solar cell absorber layers. Material investigations include...

    Abstract:
    The objective of the work reported herein is to explore the impact of decreasing channel thickness on radio-frequency (RF) sputtered amorphous indium-gallium-zinc oxide (a-IGZO) thin-film transistors (TFTs) electrical performance through the evaluation of drain current versus gate voltage (I[subscript D] − V[subscript G]) transfer curves. For a fixed set of...

  • Modeling and development of p-type thin-film transistors

    Creator:
    Spiegelberg, Matthew Craig
    Abstract:
    The primary focus of this thesis involves modeling and development of p-type thin-film transistors (p-TFTs), moving towards the realization of a filly transparent thin-film transistor (TTFT). The modeling portion of this thesis emphasizes the development of physics-based TFT models, specifically focusing on the elucidation of non-ideal current-voltage characteristic behavior. A...

  • ACTFEL device simulation with impact ionization using a two-sheet charge model

    Creator:
    Bouchard, Anthony F.
    Abstract:
    The main achievement of this thesis is the development of a two-sheet charge simulation model with space charge creation by trap-to-band impact ionization to describe the electrical characteristics of alternating-current thin-film electroluminescent (ACTFEL) devices. The two-sheet charge model localizes all of the space charge in the phosphor region of an...

  • Diamond-like carbon films for electroluminescent applications

    Creator:
    Kim, Seung-bae
    Abstract:
    White electroluminescence (EL) was observed for the first time from diamond-like carbon (DLC) films at room temperature. Electroluminescence was observed by the application of ac voltages in excess of 200 V to a metal-insulator- semiconductor (i.e. DLC)-insulator-metal (MISIM) device structure. For EL applications, three types of the DLC films were...
