Book Description
A series of free standing films of doped polypyrrole were prepared and characterized by infrared spectroscopic methods. The frequency dependence of the infrared reflectivity of the polymer films was fit to the Drude model for the dielectric function an electron gas. In order to adequately model the observed reflectance spectra, an additional oscillator term was added to the dielectric function to account for electronic transitions that involve mid gap electronic states. Approximate values for the plasma resonance frequency for these materials range between 1-4 x 10 to the -15th /s, while values for the carrier scattering time were on the order of 10 to the -15/s. The spectral analysis also allowed for the calculation of the complex dielectric constants. These constants appeared to scale with the dc conductivity of the polymer film. It is suggested that the very short carrier scattering time in conducting polymers limits the observed conductivity and that improvements in conducting polymer synthesis and processing techniques will ultimately result in much higher conductivity levels.

Book Description
The aim of this project initially was to develop accurate non-parametric methods for determining the energy band structure of semi-conducting polymers and then to incorporate within the same model a method to determine the electron levels due to impurity atoms used as replacements for the side groups about the polymer back bone. Secondly, we were to study the energy structure of several polymers with and without impurity side groups. These tasks have been successfully accomplished. (Author).

Book Description
Conjugated polymers have important technological applications, including solar cells and light emitting devices. They are also active components in many important biological processes. In recent years there have been significant advances in our understanding of these systems, owing to both improved experimental measurements and the development of advanced computational techniques. The aim of this book is to describe and explain the electronic and optical properties of conjugated polymers. It focuses on the three key roles of electron-electron interactions, electron-nuclear coupling, and disorder in determining the character of the electronic states, and it relates these properties to experimental observations in real systems. A number of important optical and electronic processes in conjugated polymers are also described. The second edition has a more extended discussion of excitons in conjugated polymers. There is also a new chapter on the static and dynamical localization of excitons.

Book Description
Polymer electronics is the science behind many important new developments in technology, such as the flexible electronic display (e-ink) and many new developments in transistor technology. Solar cells, light-emitting diodes, and transistors are all areas where plastic electronics is likely to, or is already having, a serious impact on our daily lives. With polymer transistors and light-emitting diodes now being commercialised, there is a clear need for a pedagogic text that discusses the subject in a clear and concise fashion suitable for senior undergraduate and graduate students. The content builds on what has been learnt in an elementary (core) course in solid state physics and electronic behaviour, but care has been taken to ensure that important aspects such as the synthesis of these polymers are not overlooked. The chemistry is treated in a manner appropriate to students of physics. Polymer Electronics presents a thorough discussion of the physics and chemistry behind this new and important area of science, appealing to all physical scientists with an interest in the field.

Book Description
A comprehensive overview of the physical mechanisms that control electron transport and the characteristics of metal-molecule-metal (MMM) junctions. As far as possible, methods and formalisms presented elsewhere to analyze electron transport through molecules are avoided. This title introduces basic concepts--a description of the electron transport through molecular junctions—and briefly describes relevant experimental methods. Theoretical methods commonly used to analyze the electron transport through molecules are presented. Various effects that manifest in the electron transport through MMMs, as well as the basics of density-functional theory and its applications to electronic structure calculations in molecules are presented. Nanoelectronic applications of molecular junctions and similar systems are discussed as well. Molecular electronics is a diverse and rapidly growing field. Transport Properties of Molecular Junctions presents an up-to-date survey of the field suitable for researchers and professionals.
