Time-resolved THz spectroscopy of conducting polymers
Résumé
We study, by terahertz time-domain and optical pump-THz probe spectroscopies, the optical and electrical properties of the PEDOT/PSTFSIK polymer. The latter is designed to get reed of some drawbacks of the well-known and widely used conducting polymer: the PEDOT/PSS. The optoelectronic properties in the THz range of both compounds are compared, as well as the relaxation mechanisms taking place after their photoexcitation by ultrashort optical pulses.
