  • Atomic Layer Deposition of Two Dimensional MoS2 on 150 mm Substrates

    Creator:
    Valdivia, Arturo Herrera
    Abstract:
    Two-dimensional transition metal dichalcogenides (TMDs) have recently come under intense investigation as building blocks for van der Waals heterostructure electronics. One of the most promising TMDs is MoS₂, which transitions from an indirect bandgap (1.3 eV) in its bulk state to a direct band gap (1.8 eV) in its single...

  • Sputter Deposition and Characterization of Transparent Conductive Oxide Thin Films and Applications in Photonics

    Creator:
    Bo, Yunfei
    Abstract:
    Transparent conductive oxides (TCOs), combining the optical transparency and electrical conducting properties, have attracted escalating research interests in recent years due to their potential for various photonic applications. The electrical and optical properties, such as carrier concentration, mobility, will strongly affect the performance of TCO-based photonic devices. In this dissertation,...

  • Applications of Magnetic Materials in Soft Robotics

    Creator:
    Davis, William M.
    Abstract:
    Magnetic materials can be used in modern soft robotics as a method for external stimulus actuation and motion control. By combining aspects of biology and mechanics, devices are fabricated to create a structure capable of complex movement. Applications that these devices are subject to can be broken down into four...

  • Ultra-energy-efficient Silicon Photonic Modulators Driven by Transparent Conductive Oxides

    Creator:
    Li, Erwen
    Abstract:
    Silicon photonics has become the most promising platform for future large-scale optical interconnect and optical computing systems due to its inherent CMOS compatibility, which brings exclusive advantages in bandwidth density, energy efficiency, and cost effectiveness. Parallel optical interconnects based on photonic integrated circuits (PICs) have the capacity to meet the...

  • Optical Sensors using Biological Photonic Crystals

    Creator:
    Squire, Kenneth James
    Abstract:
    This dissertation focuses on the application of diatom frustules, the biosilica shell of an algae possessing physical and photonic properties capable of enhancing optical signals, for the enhancement of optical sensing. In this work, we incorporate diatom frustules into biosensors for signal enhancement and improved target molecule detection. The potential...

  • Surface-Enhanced Infrared Absorption Gas Sensing Incorporating Advanced Plasmonic Nanostructures and Nano-Composite Materials

    Creator:
    Chong, Xinyuan
    Abstract:
    This dissertation focuses on extending the application scope of surface enhanced infrared absorption spectroscopy to gas sensing. The method we propose is incorporating plasmonic nanostructures with nano-composite material, metalorganic framework, which can selectively preconcentrate certain gas molecules into the nanopores. The preconcentrating property is first demonstrated by applying metal-organic framework...
