  • Light-matter interactions : from the photophysics of organic semiconductors to high spatial resolution optical tweezer-controlled nanoprobes

    Creator:
    Kendrick, Mark J.
    Abstract:
    Studies of light-matter interactions in organic semiconductors and in optical tweezer trapping of nanoparticles are presented. In the research related to organic semiconductor materials, a variety of novel materials and their composites have been characterized, and physical mechanisms behind their optoelectronic properties have been established. Three novel functionalized hexacene derivatives...

  • Architectural support for multithreading on a 4-way multiprocessor

    Creator:
    Kim, Gwang-Myung
    Abstract:
    The microprocessors will have more than a billion logic transistors on a single chip in the near future. Several alternatives have been suggested for obtaining highest performance with billion-transistor chips. To achieve the highest performance possible, an on-chip multiprocessor will become one promising alternative to the current superscalar microprocessor. It...

  • Nonlinear terahertz spectroscopy of carbon nanomaterials and semiconductor nanostructures

    Creator:
    Paul, Michael Jason
    Abstract:
    This thesis will cover my work relating to the developing field of terahertz (THz) science and technology. It will present experimental and theoretical studies investigating the optical and electrical properties of various material systems using novel THz imaging and spectroscopy techniques. Due to its low photon energy, THz imaging and...

  • Generation of narrowband THz pulses and THz studies of ultrafast phenomena in semiconductor quantum wells

    Creator:
    Danielson, Jeremy R.
    Abstract:
    This work comprises two main parts: creating and shaping narrowband, pulsed THz radiation in a table-top optical setup; and applying THz pulses to semiconductor nanostructures to study electron dynamics. I developed a scheme to shape the THz output of a fanned-out periodically poled lithium niobate (PPLN) crystal. The pulses are...

  • Design and computer aided optimization of a fully integrated CMOS RF distributed amplifier

    Creator:
    Ballweber, Brian M.
    Abstract:
    Advancements in the sophistication and complexity of modern electronic systems are creating a need for highly integrated systems with ever higher operational frequencies. The economical demands of these systems dictate that they be implemented using low cost fabrication technologies, such as digital CMOS. One of the major challenges facing circuit...

  • High efficiency delta-sigma modulation data converters

    Creator:
    Lee, Kyehyung
    Abstract:
    Enabled by continued device scaling in CMOS technology, more and more functions that were previously realized in separate chips are getting integrated on a single chip nowadays. Integration on silicon has opened the door to new portable wireless applications, and initiated a widespread use of these devices in our common...

  • Monte Carlo Radiation Transfer Simulations of Gamma Ray Burst Prompt Emission

    Creator:
    Parsotan, Tyler M.
    Abstract:
    Gamma Ray Bursts (GRBs) are the most energetic explosions in the Universe, producing up to $\sim10^{53}$ ergs of energy in the first few seconds of their emission -- the so-called prompt phase that is dominated by high energy X-ray and $\gamma$-ray photons. The very large luminosities released in these events...

  • Optical Development and Materials Applications of Tunable Femtosecond Stimulated Raman Spectroscopy

    Creator:
    Zhu, Liangdong
    Abstract:
    To obtain a mechanistic understanding of the chemical processes, techniques that offer a frame-by-frame visualization of molecular structure during a reaction are of vital importance. Numerous efforts and advances have been made in order to acquire such vivid molecular “movies”, especially in the electronic excited state. Ultrafast molecular spectroscopy method...

  • Comparison of carbon nanotube and graphene field-effect transistor biosensors

    Creator:
    Saltzgaber, Grant William
    Abstract:
    Detection of biomolecules is important for the diagnosis and treatment of diseases. Low concentration detection, specific biomolecule detection, and point-of-care use are appealing characteristics for biosensors because of the possibility of early detection and quick results of specific biomolecules. Furthermore, inexpensive biosensors are appealing so that they are accessible to...

  • Gene Activation Strategies in Filamentous Fungi for Natural Products Discovery

    Creator:
    Adpressa, Donovon A.
    Abstract:
    Fungi have long been a prolific source of clinically approved drugs. The antibiotic penicillin, the cholesterol lowering statins, and the immunosuppressant cyclosporine have changed the treatment of human diseases in the last century. Recently, genome analysis of filamentous fungi has revealed that the biosynthetic potential for natural product expression is...
