Book Description
This volume concentrates on the controversy within the scientific community over how to explain, understand and describe the photophysics/photochemistry of this class of materials.This controvery is of such a fundamental nature that the solution of the problem might be in a unification of the semiconductor and metal physics with the molecular quantum chemistry. Thus, a wide-ranging and comprehensive discussion of this very crucial issue has not been written down yet.This volume brings together the most prominent scientists specializing in this controversial topic. Each contributor addresses the opponents' arguments. After short introductory chapters, the contributors discuss their own speciality area and compare the results with both models and explain their position on why one of the models is more appropriate. Special emphasis is given to comparative discussions with other conjugated molecular systems as well as inorganic semiconductors.

Book Description
Carbon based pi-conjugated materials offer a broad range of applications, going from molecular electronics and single molecule devices to nanotechnology, plastic electronics and optoelectronics. The proper physical description of such materials is in between that of molecular solids and that of low-dimensional covalent semiconductors. This book is a comprehensive review of their elementary excitations processes and dynamics, which merges the two viewpoints, sometimes very different if not contrasting. In each chapter, a broad tutorial introduction provides a solid physical background to the topic, which is further discussed based on recent experimental results obtained via state-of-the-art techniques. Both the molecular, intra-chain character and the solid state, inter-molecular physics is addressed. Reports on single molecule and single polymer chain spectroscopy introduce the on-site phenomena. Several chapters are dedicated to nano-probes, steady state and transient spectroscopies. The highly ordered state, occurring in single crystals, is also discussed thoroughly. Finally, less conventional tools such as THz spectroscopy are discussed in detail. The book provides a useful introduction to the field for newcomers, and a valid reference for experienced researchers in the field.

Book Description
Recent progress in organic and LED structures, in photorefractive response in molecular ferromagnetism, as well as the ultrafast and large non-linear optical response in conjugated systems are attracting great interest from the scientific community. The discovery of fullerenes has added further impetus to this field. Two areas bear particular promise for the development of a new electronics based on SEM materials: the integration of organic materials into the planar silicon technology such as, for instance, the advances in "all organic" field-effect transistors (FET) and the new organic light emitting diodes (LED); and secondly the appearance of a totally new electronics in which photons, rather than electrons, carry the information and SEM materials act as switching devices. Both aspects and more are covered in this volume. The quality of the 52 contributions attests to the fact that this subject area has progressed from the level of a scientific curiosity to a mature field of materials science introducing important technological perspectives for electronic applications.

Book Description
The synchrotron light source is becoming widely available, after its evolution from its infancy in the sixties to the present third generation source with insertion devices. It is timely to examine the impact that synchrotron light has made and will continue to make on chemical research. With this objective in mind, the editor of this invaluable book invited contributions from practitioners who are in the forefront of the research. The book summarizes most of the significant developments in the last decade in chemical and related research using synchrotron light. The utilization of the light as a probe as well as an energy source is emphasized.This book is organized into two parts, in order of increasing photon energy. Part I deals with the applications of low energy photons and covers areas such as gas phase photodissociation reactions and dynamics, soft X-ray fluorescence, IR and photoemission analysis of surfaces, spectroscopy of organic and polymeric materials, catalysts, electronic and magnetic materials, and spectromicroscopy. Part II encompasses applications using soft to hard X-rays, including spectroscopy of surface and thin films, XAFS, diffraction and scattering, and several technological applications, namely the microprobe, photoetching and tribology.
