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.

The field of semiconducting polymers has attracted many researchers from a diversity of disciplines. Printed circuitry, flexible electronics and displays are already migrating from laboratory successes to commercial applications, but even now fundamental knowledge is deficient concerning some of the basic phenomena that so markedly influence a device's usefulness and competitiveness. This two-volume handbook describes the various approaches to doped and undoped semiconducting polymers taken with the aim to provide vital understanding of how to control the properties of these fascinating organic materials. Prominent researchers from the fields of synthetic chemistry, physical chemistry, engineering, computational chemistry, theoretical physics, and applied physics cover all aspects from compounds to devices. Since the first edition was published in 2000, significant findings and successes have been achieved in the field, and especially handheld electronic gadgets have become billion-dollar markets that promise a fertile application ground for flexible, lighter and disposable alternatives to classic silicon circuitry. The second edition brings readers up-to-date on cutting edge research in this field.

From materials to applications, this ready reference covers the entire value chain from fundamentals via processing right up to devices, presenting different approaches to large-area electronics, thus enabling readers to compare materials, properties and performance. Divided into two parts, the first focuses on the materials used for the electronic functionality, covering organic and inorganic semiconductors, including vacuum and solution-processed metal-oxide semiconductors, nanomembranes and nanocrystals, as well as conductors and insulators. The second part reviews the devices and applications of large-area electronics, including flexible and ultra-high-resolution displays, light-emitting transistors, organic and inorganic photovoltaics, large-area imagers and sensors, non-volatile memories and radio-frequency identification tags. With its academic and industrial viewpoints, this volume provides in-depth knowledge for experienced researchers while also serving as a first-stop resource for those entering the field.

This book contains the majority of the papers presented at the NATO Ad vanced Research Workshop (ARW) held in Burlington, Vermont, USA on October 12-15, 1992. This ARW was the first of its kind to address the subject of intrinsically conducting polymers with an emphasis on processing and technological applications. The NATO ARW format was followed in that the subjects addressed here were limited in number but discussed in detail with the attendance being limited to a small number of selected scientists. The ARW brought together lecturers who are leaders in their respective fields from a wide range of NATO and non-NATO countries (a total of 11 countries) with the support of the NATO Scientific Affairs Division and some support from Champlain Cable Corporation. The total number of par ticipants was 33 and the number of presentations was 24. The speakers were chosen based on the topics selected for this workshop and repre sented industry, universities and government laboratories. The field of conducting polymers has grown rapidly during the past few years with important developments in materials processing and fabrica tion that brought about active research programs focusing on the use of these polymers as "smart" materials in technological applications and devices in academic and industrial research laboratories.

This book reviews the current understanding of electronic, optical and magnetic properties of conjugated polymers in both the semiconducting and metallic states. It introduces in particular novel phenomena and concepts in these quasi one-dimensional materials that differ from the well-established concepts valid for crystalline semiconductors. After a brief introductory chapter, the second chapter presents basic theore tical concepts and treats in detail the various models for n-conjugated polymers and the computational methods required to derive observable quantities. Specific spatially localized structures, often referred to as solitons, polarons and bipolarons, result naturally from the interaction between n-electrons and lattice displacements. For a semi-quantitative understanding of the various measure ments, electron-electron interactions have to be incorporated in the models; this in turn makes the calculations rather complicated. The third chapter is devoted to the electrical properties of these materials. The high metallic conductivity achieved by doping gave rise to the expression conducting polymers, which is often used for such materials even when they are in their semiconducting or insulating state. Although conductivity is one of the most important features, the reader will learn how difficult it is to draw definite conclusions about the nature of the charge carriers and the microscopic transport mechanism solely from electrical measurements. Optical properties are discussed in the fourth chapter.
