  • 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,...

  • 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...

  • 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...

  • Leveraging Compressive Sampling and Machine Learning for Adaptive and Cooperative Wideband Spectrum Sensing

    Creator:
    Zaid, Adem
    Abstract:
    This thesis proposes a novel technique that exploits spectrum occupancy behaviors inherent to wideband spectrum access to enable efficient cooperative spectrum sensing. The proposed technique reduces the number of required sensing measurements while accurately recovering spectrum occupancy information. It does so by leveraging compressive sampling theory to exploit the block-like...

  • 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...

  • 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...

  • Optofluidic Sensing from Inkjet-Printed Droplets on Diatom Biosilica

    Creator:
    Xi, Yuting
    Abstract:
    We explored an optofluidic sensing mechanism from inkjet-printed droplets on diatom biosilica using surface-enhanced Raman scattering (SERS). Our study revealed a new biosensing strategy that combines the microscopic fluidic flow induced by the droplet evaporation and the photonic crystal effects of diatom frustules, which can provide an ultra-sensitive, cost-effective biosensing...

  • 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...
