  • Optical Tweezers-Based Probe of Charge Transfer in Organic Semiconductors at Microscopic Scales

    Creator:
    Busche, Jacob A.
    Abstract:
    A method for measuring the (dis)charging dynamics of organic semiconductors with single-electron resolution in multiple environments is developed using optical tweezers. A 1μm silica bead was coated with either a pristine organic semiconductor or an electron donor-acceptor blend, trapped using optical tweezers, and driven with an oscillating electrical driving force....

  • 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...
