Solid-state structure formation and functional properties of semiconducting polymers and composites for TFTs
Abstract/Contents
- Abstract
- Polymer semiconductors (PSCs) have experienced great innovation alongside the development of soft and wearable electronics on account of their mechanical ductility, synthetic versatility, and ease of processing from solution. The design of flexible integrated circuits based on PSCs relies on an understanding of PSC solid-state structure formation during deposition from solution. Although many useful frameworks have been developed to describe the behavior of well-studied commodity plastics (e.g. polyethylene, polystyrene), the extension of these descriptions to PSCs, typically comprised of uniquely rigid conjugated backbones and flexible alkyl sidechains, remains a persistent challenge. This dissertation describes the use of complementary characterization techniques to develop a more descriptive picture of solid-state structure formation in single-component and composite solution-deposited thin films of recently reported high-performance PSCs. Specifically, grazing incidence x-ray diffraction, UV-visible absorption spectroscopy, atomic force microscopy, rheology, and x-ray photoelectron spectroscopy measurements are combined. Insights into solid-state structure formation are correlated to functional properties. We investigate (1) the impact of thin-film morphology on thin-film mechanics during tensile deformation and (2) the impact of single-component and composite morphologies on the device performances of strained and unstrained thin-film transistors, which are the basic units of integrated circuits.
