  • 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...

  • 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...

  • 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...

  • Exploring the Optical and Electronic Properties of Xylindein, a Fungus-Derived Pigment, as a Sustainable Organic Semiconductor

    Creator:
    Quinn, Alexander
    Abstract:
    Xylindein is an organic pigment derived from Chlorociboria aeruginascens and C. aeruginosa fungi that has shown promise as an organic semiconductor. Preliminary estimates of charge carrier mobilities (CCMs) on the order of 0.1 cm2/Vs were calculated from early tests on xylindein thin films, and photocurrents were also observed under laser...

  • Photodimerization of Organic Semiconductors in the Strong Coupling Regime

    Creator:
    Puro, Richard
    Abstract:
    Organic semiconducting materials have emerged in the last few decades as viable alternatives to inorganics in broad applications from field effect transistors to LEDs to solar cells. Organics provide many benefits over inorganics such as flexibility, sustainability, and reduced cost. However, these materials are more susceptible to degradation in the...

  • Polarization Dependent Spectral Analysis Reveals Dipole Alignment and Intermolecular Coupling in Anthradithiophene Organic Semiconducting Crystals

    Creator:
    Lam, Andrew
    Abstract:
    Organic photovoltaics are being explored as the next generation material for semiconducting and optoelectronic devices but are limited by their stability and efficiency. One new candidate is crystallized Anthradithiophene (ADT), which is a promising photo-voltaic material due to its high quantum yield and adjustable side groups. The side derivatives TES-F,...

  • 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...
