Anisotropic Charge Conduction in Oriented Donor-Acceptor Polymer Films and Liquid Dispersions Measured by Time-Resolved Terahertz Spectroscopy

Time-Resolved Terahertz methods with polarized pump-probe analysis are employed to extract conduction and mobility anisotropy of conjugated donor-acceptor polymers as films and liquid dispersions. Nano-grooved substrates with bladed films yield high in-chain conduction anisotropy compared to near is...

Description
Summary:Time-Resolved Terahertz methods with polarized pump-probe analysis are employed to extract conduction and mobility anisotropy of conjugated donor-acceptor polymers as films and liquid dispersions. Nano-grooved substrates with bladed films yield high in-chain conduction anisotropy compared to near isotropic drop-cast films and polymers in toluene.
