  • Co-planar integration of silicon integrated circuits and microfluidic networks for biosensor applications

    Creator:
    Lindsay, McKay W.
    Abstract:
    Silicon integrated circuit (IC) technology has enabled numerous electrical and optical sensors used in biological and chemical assays, where they can increase performance while decreasing cost and size compared to traditional detectors. There is significant potential to further leverage IC technology for lab-on-chip applications, creating affordable and portable medical diagnostic...

  • Point-of-care and wearable sensors for non-invasive stress hormone detection with molecularly imprinted techniques

    Creator:
    Yeasmin, Sanjida
    Abstract:
    Rapid and sensitive detection of stress hormones, such as cortisol and dehydroepiandrosterone (DHEA), can benefit the diagnosis of diseases related to adrenal gland disorders, post-traumatic stress disorders, chronic fatigue syndrome, and more. Stress hormones fluctuate in a circadian rhythm, the highest in the early morning and the lowest at night;...

  • Non-enzymatic electrochemical sensors based on functionalized nanomaterials

    Creator:
    Wu, Bo
    Abstract:
    Unlike other biosensing, electrochemical biosensor has the advantages of robustness, easy miniaturization, excellent detection limits, and capability in handling small analyte volumes. The detection selectivity of the electrochemical biosensors is mainly supported by bioreceptors. However, these receptors always suffer from the performance variation caused by the environment and the thermal-...

  • 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...

  • Hybrid electric vehicle dc-bus converter harmonics

    Creator:
    Mills-Price, Michael A.
    Abstract:
    As more advanced hybrid electric vehicles begin emerging onto the commercial market, design algorithms for their control become increasingly more complicated. One major hurdle for designers is the mitigation and control of the created high frequency harmonics caused from switching the dc voltage into an ac voltage by use of...

  • Quantitative Analysis of Illicit Drug Residues from Wastewater using Surface-enhanced Raman Scattering

    Creator:
    Zhang, Boxin
    Abstract:
    Detection of illicit drug residues from wastewater provides a new route toward community level assessment of drug abuse that is critical to public health. However, traditional chemistry analytical tools such as liquid chromatography in tandem with mass spectrometry cannot meet the large-scale testing requirement in terms of cost, throughput, and...

  • 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...

  • Performance-improving techniques for wireless systems

    Creator:
    Ozdural, Orhan Can
    Abstract:
    In this thesis, maximum likelihood Doppler frequency estimation and phase noise suppression algorithms for Orthogonal Frequency Division Multiplexing (OFDM) systems are presented. A novel handover decision algorithm for wireless systems, called predictive base station switching (PBSS), is also introduced. The maximum Doppler Frequency is the ratio of the speed of...

  • Investigation of ultra-thin In-Ga-Zn-O thin-film transistors

    Creator:
    Chiang, Tsung-Han
    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...

  • 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...
