Book Description
In recent years it has become increasingly appreciated that fundamentally nonlinear excitations - solitons - play an essential role in an incredible variety of natural systems. These solitons, which frequently exhibit remarkable stability under interactions and perturbations, often dominate the transport, response, or structural properties of the systems in which they occur. In this article, we present an introduction to the solitons that occur in quasi-one-dimensional conducting polymers (synmetals) and related systems. The relevance of this subject to molecular electronic devices is twofold. First, many of these materials have molecular structures similar to possible prototype molecular switches. Second, to understand in detail how a molecular electronic device could work, it is essential to have a broad perspective on the nature of possible excitations in a variety of natural and synthetic molecular materials. 51 references.

Conjugated Conducting Polymers
Author: Helmut Kiess
Publisher: Springer Science & Business Media
ISBN: 3642467296
Category : Science
Languages : en
Pages : 320
Book Description
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.

Pages : 268
Book Description
An authentic revolution took place in the area of solid-state chemistry and physics just after World War II. The century of solid state started from the modest beginnings of the transistor at Bell Laboratory. Since then, the area of science and technology has been directed primarily toward the study of alloys, ceramics, and inorganic semiconductors. The size of electronic devices became smaller and smaller, while the dimensionality of materials was also reduced just after the invention of the integrated circuit. It is at this point that the advent of the discovery of quasi one-dimensional conductors has opened up a whole new area of ''nonclassical'' solid-state chemistry and physics. In the modern world, plastic and electrical devices are always tightly integrated together. However, it was in 1977 that an electrically conductive, quasi one-dimensional organic polymer, polyacetylene, was discovered. During the past 30 years, a variety of different conducting polymers have been developed. Excitement about these polymeric materials is evidenced by the fact that the field of conducting polymers has attracted scientists from such diverse areas of interest as synthetic chemistry, electrochemistry, solid-state physics, materials science, polymer science, electronics, and electrical engineering.
