  • Electrical characterization of silicon and silicon dioxide materials

    Creator:
    Sze, Wing-Il
    Abstract:
    The major goal of this research work was to develop better electrical measurements for the evaluation of silicon material quality. The first approach investigated was the Zerbst generation lifetime measurement technique. It was demonstrated that the error in the estimation of the generation lifetime obtained with this technique could be...

  • NMR studies of CdF₂:Ga and CdF₂:Ga,Y

    Creator:
    Hilger, Derrick J.
    Abstract:
    Crystals of CdF₂:In and CdF₂:Ga reduced in a cadmium vapor exhibit unusual metastable properties that can be explained by a "negative U" model. This work uses NMR to investigate this model for CdF₂:Ga and CdF₂:Ga,Y and compare the results to optical measurements. Temperature dependent relaxation measurements were done on ¹¹³Cd...

  • Recombination and generation lifetime characterization of p/p⁺ epitaxial silicon wafers

    Creator:
    Aminzadeh, Mehran G.
    Abstract:
    The refresh times of all dynamic charge storage devices, best characterized by the generation lifetime at roan temperature and the recombination lifetime at higher device operating temperatures (T>70°C), strongly influence the efficient and successful operation of dynamic charge storage devices such as DRAM's and CCD's. Both recombination and generation lifetime...

  • Local field effects on dielectric properties of solids

    Creator:
    Canfield, Lingzhou Li
    Abstract:
    Local field effects on the dielectric properties of solids have been studied for three-dimensional and two-dimensional crystals by using two kinds of dipole models: an atomic dipole model in which dipoles coincide with atom sites and a bond dipole model in which dipoles are placed along bond directions. Local fields...

  • First principles studies of optical, electronic and mechanical properties of organic molecules and solids

    Creator:
    Barras, Faye Lyn
    Abstract:
    This thesis presents the results of quantum-mechanical first principles calculations of optical, electronic and mechanical properties of organic molecules and solids, which have diverse potential applications such as photovoltaics, flexible electronics, and mechanical catalysts with applications in force sensors and self-healing materials. The electronic and optoelectronic properties of organic thin...
