Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Conjugated Conducting Polymers written by Helmut Kiess and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Peierls Ground State Solitons and Polarons in Ring Containing Polymers written by and published by . This book was released on 1992 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report of doping of polyacetylene to form a highly conducting polymer opened the question concerning the nature of the electronic states of the polymer backbone that are formed upon charge transfer between the polymer and dopant backbone. Extensive study of polyacetylene has demonstrated that this system is a degenerate Peierls semiconductor with a bandgap introduced through bond alternation. Pernigraniline is a semiconductor analogous to trans- polyacetylene. However, it differs from polyacetylene in that the overlap between adjacent sites can be modulated by both changes in bond length and changes in ring torsion angle. It is shown that as a result of these two independent order parameters there are differing types of charge excitation possible on pernigraniline backbone, with both bond order excitations such as bond order solitons and ring torsion excitations such as ring torsion polarons possible. Recent photoexcitation spectroscopy studies have confirmed the presence of both bond order solitons and ring rotation polarons.
