An Infrared Probe of Charge Dynamics in High Mobility Organic Semiconductors

Abstract

This program was focused on several novel experimental approaches to investigating charge injection and charge transport in organic semiconductors all using infrared (IR) spectroscopy. IR spectroscopy was employed to characterize polymer systems integrated in the architecture of organic field-effect transistors (OFET). These experiments allowed the PI to determine: i) the excitations of the studied organic semiconductors, and ii) their dynamics in high mobility OFETs. The PI proposed to investigate modification of the electronic properties at the surface of organic semiconductors controlled by self-assembled monolayers (SAM) and has completed this work. In addition, the PI has completed a comprehensive study of high mobility, low band gap of Donor-Acceptor (D A) copolymers that are of high interest in view of ambipolar transport in these systems.
