Beschreibung
Ideal resource for learning about the fundamentals of organic semiconductors and their device applications with minimal prior knowledge Assuming only basic knowledge of excitations in molecules and semiconductors, Electronic Processes in Organic Semiconductors comprehensively explains the electronic structure of organic semiconductors, the flow of charges and the nature of excited states, and the intricacies of the electronic and optical processes. The text is complemented by feature boxes detailing aspects that may be trivial to one group of readers yet fully unknown another, as the book is intended for chemists, physicists, material scientists, engineers and biologists alike. The book is structured into four chapters. Chapter one introduces the reader to basic concepts of molecular photophysics. Chapter two explores how interactions between chromophores affect charges and excited states. Chapter three delineates the processes that are relevant to optoelectronic devices. Chapter four discusses how charge carrier transport, recombination and exciton dissociation can be employed in the operation of organic semiconductor devices. This newly revised and updated Second Edition responds to the development of novel material classes and the increase in bioelectronic applications. It reflects the advanced insight on electronic structure, charge transport, excitonic processes and the key role played by film morphology in this. Sample topics covered in Electronic Processes in Organic Semiconductors include: * Electronic, vibrational, and spin factors in transitions between molecular states * Experimental methods to study charge transport and excited states, comprising spectroscopic techniques as well as device-based measurements * Mechanisms of charge generation and transport in undoped and doped systems * Properties of excitations in single-compound materials, donor-acceptor systems and host-guest systems * Basics of device fabrication for solar cells, light-emitting diodes and transistors, operational principles, performance assessment and approaches for further improvement Written in a way that makes understanding of organic semiconductors easy even for the uninitiated, the Second Edition of Electronic Processes in Organic Semiconductors continues to be the go-to resource for students intending to learn about organic semiconductors. It also serves as key reference for scientists from adjacent fields that need information on a particular aspect of organic semiconductors.
Autorenporträt
Anna Köhler has been Professor and Chair of Experimental Physics II at the University of Bayreuth, Germany, since 2007. After completing her PhD 1996 with Sir Richard Friend at the University of Cambridge, UK, she held Research Fellowships at Peterhouse, Cambridge, and at the Royal Society, UK. She was appointed Professor at the University of Potsdam, Germany, in 2003. Her research centres on the photophysical properties of organic semiconductors, with a focus on energy and charge transfer processes in singlet and triplet excited states. Heinz Bässler is retired Professor at the Bayreuth Institute of Macromolecular Research (BIMF) at the University of Bayreuth, Germany. From 1970 to 2002 he worked as Professor in the Department of Physical Chemistry at the Philipps University in Marburg in Germany, having obtained his PhD degree in Physics from the Technical University in Munich, Germany, in 1963. His research interest concerns the optoelectronics of organic solids with particular emphasis on charge transport and on the spectroscopy of conjugated polymers. He is widely recognized for his studies on the effects of disorder in organic semiconductors.
