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. 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. 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. Topological defects and transport and optical properties are then addressed, and one of the most commonly used transparent conducting polymers, PEDOT:PSS, is described in some detail as a case study.ĭownload Polymer Electronics Book in PDF, Epub and Kindle After addressing some basic topics in solid state physics, a comprehensive introduction to molecular orbitals and band theory leads to a description of computational methods based on Hartree-Fock and density functional theory (DFT), for predicting geometry conformations, frontier levels and energy band structures. The text is intended to assist graduate students and researchers in the field of organic electronics to use theory to design more efficient materials for organic electronic devices such as organic solar cells, light emitting diodes and field effect transistors. Written in the perspective of an experimental chemist, this book puts together some fundamentals from chemistry, solid state physics and quantum chemistry, to help with understanding and predicting the electronic and optical properties of organic semiconductors, both polymers and small molecules. This text is suitable for advanced undergraduate and graduate students in materials science and engineering, and for those studying semiconductor physics.ĭownload Electronic Structure of Organic Semiconductors Book in PDF, Epub and Kindle The authors preface their treatment with an introduction to semiconductor materials and conclude with a chapter on point defect maldistributions. These topics are among the central issues in the investigation and applications of semiconductors and in the operation of semiconductor devices. The basic properties of extended defects (dislocations, stacking faults, grain boundaries, and precipitates) are outlined, and their effect on the electronic properties of semiconductors, their role in semiconductor devices, and techniques for their characterization are discussed. This book surveys the properties, effects, roles and characterization of extended defects in semiconductors. The elucidation of the effects of structurally extended defects on electronic properties of materials is especially important in view of the current advances in electronic device development that involve defect control and engineering at the nanometer level. This monograph will be of interest to physicists, chemists, and materials scientists.ĭownload Extended Defects in Semiconductors Book in PDF, Epub and Kindle The book also examines the thermochemistry of semiconductors before concluding with a concise qualitative description of barriers, junctions, and devices, with emphasis on the physical and chemical principles behind their operation. Subsequent chapters introduce the reader to elastic and piezoelectric constants as well as lattice vibrations, energy bands, impurities, and fundamental optical spectra. The discussion then turns to the effects of covalent and ionic bonds on crystal structures and cohesive energies of semiconductors, paying particular attention to the electronic configurations of atoms, ionicity, and homopolar energy gaps. Comprised of 10 chapters, this book begins with an overview of the crystal structures of the more common and more useful semiconductors, together with bonding definitions and rules bond energy gaps and band energy gaps tetrahedral coordination and bond lengths and radii. Lattice vibrations, energy bands, and the thermochemistry of semiconductors are also discussed, along with impurities and fundamental optical spectra. Download Bonds and Bands in Semiconductors Book in PDF, Epub and Kindleīonds and Bands in Semiconductors deals with bonds and bands in semiconductors and covers a wide range of topics, from crystal structures and covalent and ionic bonds to elastic and piezoelectric constants.
