Overview

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 with worked examples and detailed computations. 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 and on exciton dissociation can be employed to the fabrication of organic semiconductor devices. This newly revised and updated Second Edition covers additional polymer materials, novel methods for determining the electronic structure and the charge carrier transport properties in organic semiconductors, further details on dissociation, diffusion, and decay of excitations, and the latest research on current organic semiconductor devices. Sample topics covered in Electronic Processes in Organic Semiconductors include: Electronic, vibrational, and spin factors in transitions between molecular states Spectroscopic methods including photoluminescence spectra, lifetimes, quantum yields, and steady state spectra Charge carrier transport, covering the time-of-flight technique, space-charge-limited currents (SCLC), and field-effect transistors (FETs) Properties of germinate pairs in single-compound materials and donor-acceptor systems Basic solar cell and light-emitting diode structures, solar cell performance, and improving charge transport in transistors 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.
