  • 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...

  • 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...

  • The design and development of the wearable health and activity monitor

    Creator:
    Glover, Neil E.
    Abstract:
    This work describes the development of an accurate, low-cost, expandable and wearable health and activity monitoring platform. Wearable monitors used to track physical activity are becoming an increasingly popular and effective way to combat our dangerously sedentary lifestyles. Unfortunately most existing wearable solutions are either costly, inaccurate or cumbersome. The...

  • 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...

  • Energy-efficient routing for delay-constrained data traffic in linear wireless sensor networks

    Creator:
    Alesaimi, Hani
    Abstract:
    Linear wireless sensor networks (LWSN) are special class of wireless sensor networks where sensor nodes are deployed in a straight line. Monitoring industrial pipelines, railroads, tunnels, power lines, and borders are applications of LWSNs. Wireless sensors are tiny devices with limited energy resources; therefore, efficient energy routing in LWSNs is...

  • Comprehensive depletion-mode modeling of oxide thin-film transistors

    Creator:
    Zhou, Fan
    Abstract:
    The primary focus of this thesis is modifying the comprehensive depletion-mode model and extending its applicability to p-channel thin-film transistor (TFT) behavior and subthreshold (subpinchoff) operation. The comprehensive depletion-mode model accurately describes depletion-mode TFT behavior and establishes a set of equations, different from those obtained from square-law theory, which can...

  • Assessment of Barrier Heights between ZrCuAlNi Amorphous Metal and SiO₂, Al₂O₃, HfO₂, and ZrO₂ using Internal Photoemission Spectroscopy

    Creator:
    Klarr, Tyler D.
    Abstract:
    As scaling of silicon (Si) based devices approaches fundamental limits, thin film metal-insulator-metal (MIM) tunnel diodes are attracting interest due to their potential for high speed operation. Because operation of these devices is based on tunneling, electrode / interfacial roughness is critical. Recently, it was shown that combining ultra-smooth bottom...

  • Autonomous Sensor Systems For Wind Turbine Blade Collision Detection

    Creator:
    Clocker, Kyle
    Abstract:
    Wind turbines serve an increasing proportion of total energy generation, with expanded onshore and offshore installations proceeding worldwide. Continued construction, expansion, and operation of wind energy installations must be managed in conjunction with effects on local and migratory wildlife, specifically bird and bat species that may be affected by wind...
