  • (Opto)electronic Properties of Xylindein and Organic (Opto)electronic Devices

    Creator:
    Giesbers, Gregory J.
    Abstract:
    Organic semiconductors are of interest for (opto)electronic applications due to their low cost, solution processability, and tunable properties. Natural product-derived organic pigments have attracted attention due to their extraordinary environmental stability and unexpectedly good optoelectronic performance, in spite of only partially conjugated molecular structures. Fungi-derived pigments are a naturally sourced,...

  • Electronic and Optical Properties of Organic Semiconductors : Experiment and Simulation

    Creator:
    Johnson, Brian
    Abstract:
    The continued development of organic semiconductor materials relies on an understanding of the relationship between optoelectronic properties, molecular structure, and molecular interaction. Several detailed studies of electronic properties in functionalized polyacene materials are presented. A computational model which allows the extraction of charge generation and transport properties from experimental data...

  • Modeling optical reflection and electric field intensity in organic semiconductor microcavities

    Creator:
    Munk, Rebecca
    Abstract:
    Organic semiconductors are a promising alternative to the traditional inorganic semiconductors, such as silicon. Organics are solution-processable, low-cost, sustainable, and have interesting optoelectronic properties. One such property is the formation of exciton-polaritons, quantum quasi-particles formed by an electron-hole pair in the semiconductor and a photon. This process can be induced...

  • Fungal Photonics

    Creator:
    Spafford, Jasper
    Abstract:
    The spalting fungus Scytalidium cuboideum secretes a red pigment that produces naphthoquinonic crystals that are a photonic material candidate. The molecule can pack together in different configurations resulting in amazingly different optical properties. I developed a procedure (slowly evaporating the solvent) to preferentially grow two of these configurations, which have...

  • A Study of Charging Behaviors in Organic Semiconductors using Optical Trapping

    Creator:
    Founds, Graham M.
    Abstract:
    We measure the charging and discharging of two organic materials, PCBM and ADT-TES-F. These materials are studied through the noncontact method of particle trapping known as Optical Tweezers, where an IR laser is used to constrain the motion of a coated or noncoated silica sphere while its positional data is...

  • Study of Organic Semiconductors Using Time-Resolved Charge Measurements at the Microscale

    Creator:
    Wallace, Richard
    Abstract:
    Understanding charge transfer in organic semiconductors is important for developing devices like organic light emitting diodes and flexible electronics. Optical tweezers have been used in many disciplines for trapping, manipulating, and analyzing microscopic objects such as microspheres, micro-organisms, and other colloidal particles. Using optical tweezers, studies have measured the average...

  • Optoelectronic Properties of a Novel Fungi-derived Pigment

    Creator:
    Wiesner, Cameron
    Abstract:
    In industry, there is considerable interest in finding sustainable, renewable materials for use in electronic devices. Pigments derived from spalting fungi are of particular interest due to their longevity in diverse environmental conditions. The focus of my project was to characterizethe properties of a novel, fungi-derived pigment, and to discover...

  • Exciton and Polariton Nature in Organic Crystals

    Creator:
    Van Schenck, Jonathan D. B.
    Abstract:
    Understanding the impact of inter-molecular orientation on the optical proper-ties of organic semiconductors is important for designing next-generation organic (opto)electronic and photonic devices. However, fundamental aspects of how various features of molecular packing in crystalline systems determine the nature and dynamics of excitons have been a subject of debate. Toward...
