Gigahertz Probing of Poly(3-hexylthiophene) With A Kilohertz Detection Scheme

ORAL

Abstract

Organic semiconducting polymers have been well studied at DC and low-frequencies, giving important information about charge transport and metal-polymer interaction. However, comparatively little is known about the operation of these polymers at radio frequencies (~1 GHz). RF frequencies can be a useful tool to investigate high-frequency mobility and charge carrier dynamics relevant for the possibility of using these polymers in RF applications. We present a novel technique that probes poly(3-hexylthiophene) (P3HT) response in the RF regime but allows for detection in the kHz regime. We show transport data of P3HT and discuss a theoretical framework for inferring behavior at GHz frequencies.
