  • Spectroscopy of biophysical, physiological and pathological responses of plant germplasm

    Creator:
    Li, Ning
    Abstract:
    Imaging spectra of plant tissues yield considerable potential and useful information for basic studies and agriculture practice. We constructed an imaging spectrophotometer with spectral range from 400 nm to 1100 nm, which was used to study various physiological events of plant germplasm: location of bundle sheath and mesophyll cells in...

  • Zinc tin oxide thin-film transistor current mirror circuits

    Creator:
    Feller, Layannah Elizabeth
    Abstract:
    The central focus of this thesis is the design, fabrication and characterization of amorphous oxide semiconductor (AOS) thin-film transistor (TFT) current mirrors. The thin-film deposition and circuit fabrication methods used to realize zinc tin oxide (ZTO) TFT current mirrors are addressed in order to elucidate the processing challenges for this...

  • Laser probe for the detection of surface acoustic waves

    Creator:
    Albers, Emory
    Abstract:
    The Amplitude and phase of surface acoustic waves can be characterized using a laser beam and photodiode detector. This paper describes a technigue for charactarizing waves using the double photodiode method. This method is a modification of the knife-edge method, and involves focusing a laser beam to a beam spot...

  • Radiation effects in compound semiconductor heterostructure devices

    Creator:
    Sarkar, Aveek, 1974-
    Abstract:
    Radiation studies were performed on compound semiconductor heterostructure devices. The objective was to understand the degradation processes caused by the exposure of these devices to radiation. Preliminary experiments were focussed on studying the degradation phenomenon in single heterojunctions and single quantum wells. It was found that ionizing radiation like gamma...

  • Analysis and modeling of planar microstrip spiral inductors on lossy substrates

    Creator:
    Lutz, Richard D.
    Abstract:
    The advent of low-cost RFIC's fabricated in Silicon-based technologies has led to the use of monolithic lumped elements which are located on-die. While it is clearly advantageous to have a high degree of integration and thus fewer off chip elements, parasitic losses due to semiconducting substrate effects can be a...

  • Analysis and modeling of microstrip on-chip interconnects on silicon substrate

    Creator:
    Lan, Hai
    Abstract:
    The electrical performance of on-chip interconnects has become a limiting factor to the performance of modern integrated circuits including RFICs, mixed-signal circuits, as well as high-speed VLSI circuits due to increasing operating frequencies, chip areas, and integration densities. It is advantageous to have fast and accurate closed-form expressions for the...

  • Modelling of on-chip spiral inductors for silicon RFICs

    Creator:
    Melendy, Daniel
    Abstract:
    In high-frequency circuit design, performance is often limited by the quality of the passive components available for a particular process. Specifically, spiral inductors can be a major bottle-neck for Voltage-Controlled Oscillators (VCOs), Low-Noise Amplifiers (LNAs), mixers, etc. For designers to correctly optimize a circuit using a spiral inductor, several frequency-domain...

  • Structural stability effects on adsorption of bacteriophage T4 lysozyme to colloidal silica

    Creator:
    Tian, Minghua
    Abstract:
    Circular dichroism (CD) spectra were obtained for bacteriophage T4 lysozyme and three of its mutants in the presence and absence of colloidal silica nanoparticles. Mutant lysozymes were produced by substitution of the isoleucine at position 3 with tryptophan, cysteine and leucine. Each substitution resulted in an altered structural stability, quantified...

  • Simulated and Experimental Characteristics of Analysis Techniques for ZrCuAlNi/AlOx/Al Metal-Insulator-Metal Tunnel Diodes

    Creator:
    Tan, Cheng
    Abstract:
    This project examines the results of current-voltage conduction mechanism analysis techniques simulated under assumed conduction conditions. Thermionic emission and Fowler-Nordheim tunneling conditions are simulated and analyzed. The resulting plots show how devices behave under different condition mechanisms. The effects of different conduction mechanisms on the results of various analysis techniques...
