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...

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....
