  • BaCuChF (Ch = S, Se, Te) p-type transparent conductors

    Creator:
    Zakutayev, Andriy
    Abstract:
    BaCuChF (Ch = S, Se, Te) materials are chalcogen-based transparent conductors with wide optical band gaps (2.9 – 3.5 eV) and a high concentration of free holes (10¹⁸ – 10²⁰ cm⁻³) caused by the presence of copper vacancies. Chalcogen vacancies compensate copper vacancies in these materials, setting the Fermi level...

  • Electrical recommendations and formulas for metal fill in radio-frequency integrated circuits

    Creator:
    Gaskill, Steven
    Abstract:
    With increasing transistor operating frequencies, interconnects and passive devices are becoming performance limiters in integrated circuit (IC) designs. To combat this, the interconnect layers above the active silicon are trending toward low-κ dielectrics and Cu metallization. The use of these new materials has popularized chemical mechanical polishing (CMP) to planarize...

  • Computational nanooptics in hyperbolic metamaterials and plasmonic structures

    Creator:
    Thongrattanasiri, Sukosin
    Abstract:
    This dissertation concerns several problems in the fields of light interaction with nanostructured media, metamaterials, and plasmonics. We present a technique capable of extending operational bandwidth of hyperbolic metamaterials based on interleaved highly-doped InGaAs and undoped AlInAs multilayer stacks. The experimental results confirm theoretical predictions, exhibiting broadband negative refraction response...

  • Label free biosensing with carbon nanotube transistors

    Creator:
    Leyden, Matthew R.
    Abstract:
    As electronics reach nanometer size scales, new avenues of integrating biology and electronics become available. For example, nanoscale field-effect transistors have been integrated with single neurons to detect neural activity. Researchers have also used nanoscale materials to build electronic ears and noses. Another exciting development is the use of nanoscale...

  • Immune radio architecture for platform interference

    Creator:
    Alban, Eduardo
    Abstract:
    The decrease of switching times accompanied by the corresponding increase of clock speeds and data rates, contributes to improve the overall system computational performance. At the same time, they also affect wireless communications due to an increment in the emissions of electromagnetic radiation on the radio bands. In this dissertation...

  • Monte Carlo studies of classical Heisenberg spins on face-centered-cubic lattices : effects of strain, interlayer coupling, and dilution of lattice

    Creator:
    Park, Seongweon
    Abstract:
    This thesis presents the results from Monte Carlo calculations on classical vector spins in face-centered-cubic (FCC) lattices. The goal of the study was to understand the effect of interlayer coupling, dilution of magnetic atoms in the lattice, and symmetry-changing strain. Experimental work by T. M. Giebultowicz et al. and J....

  • Hydrogen/deuterium exchange mass spectrometry as a technology platform for studying conformational dynamics in large protein complexes

    Creator:
    Nirudodhi, Sasidhar N.
    Abstract:
    Proteins are essential to all biological systems. Proteins participate in numerous cellular processes by interacting with other proteins, other metabolites and membranes in a dynamic environment. Studying the structural and conformational properties of proteins in the solution phase is necessary to understand their protein folding and interaction dynamics. This research...

  • Scanning photocurrent microscopy study of photovoltaic and thermoelectric effects in individual single-walled carbon nanotubes

    Creator:
    DeBorde, Tristan
    Abstract:
    Carbon Nanotubes are a unique family of nanostructures that have shown remarkable promise for mechanical, electrical, and optical applications. Fundamentally similar to the earlier discovered Buckminsterfullerene (C₆₀), carbon nanotubes are hollow cylinders formed from a single sheet of carbon atoms. The research presented in this dissertation investigates several carbon nanotube...

  • 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...

    Harthcock, Colin
    Abstract:
    In this dissertation, I describe spectroscopic studies of jet-cooled polycyclic aromatic hydrocarbons (PAH) and one nitrogen substituted PAH (PANH) using pulsed field zero kinetic energy (ZEKE) photoelectron spectroscopy and resonantly enhanced multiphoton ionization (REMPI) spectroscopy. Recently, there has been a demand for far-infrared (FIR) spectral information of astrophysically relevant molecules...
