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...
