  • Generating and using terahertz radiation to explore carrier dynamics of semiconductor and metal nanostructures

    Creator:
    Jameson, Andrew D.
    Abstract:
    In this thesis, I present studies in the field of terahertz (THz) spectroscopy. These studies are divided into three areas: Development of a narrowband THz source, the study of carrier transport in metal thin films, and the exploration of coherent dynamics of quasi-particles in semiconductor nanostructures with both broadband and...

  • Terahertz Imaging and Nonlinear Spectroscopy of Semiconductors using Plasmonic Devices

    Creator:
    Thompson, Zachary James
    Abstract:
    In this dissertation, a series of studies in the field of terahertz (THz) science are presented, specifically using nonlinear THz spectroscopy. We exploit huge field enhancement and subwavelength confinement in plasmonic structures. There are three distinct projects which will be discussed: nonlinear THz spectroscopy using plasmonic induced transparency (PIT), THz-triggered...

  • 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...
