OPTOELECTRONICS

相關熱銷的書籍推薦給您

Optoelectronics is a practical and self-contained graduate-level text on the subject. The authors include such topics as quantum mechanics of electron-photon interaction, quantization of the electro-magnetic field, semiconductor properties, quantum theory of heterostructures and nonlinear optics. They build on these concepts to describe the physics, properties and performances of light-emitting diodes, quantum well lasers, photodetectors, optical parametric oscillators and waveguides. The emphasis is on the unifying theoretical analogies of optoelectronics, such as equivalence of quantization in heterostructure wells and waveguide modes, entanglement of blackbody radiation and semiconductor statistics.

This textbook consists of six chapters. The first chapter highlights the concept of liquid crystals, including chemical structure, phase classification, defect and texture, and continuum theory. It has been carefully written to meet the needs of readers who do not specialize in liquid crystals. The second chapter is related to the theoretical description of liquid crystalline polymers, networks, and gels, which deals with subjects such as the formation of liquid crystallinity in the polymer system, the phase transition and phase diagram, the molecular weight effect, chain conformation, physics properties, etc. In Chapter 3, the molecular engineering of liquid crystalline polymers is introduced. The molecular composition and the molecular weight play essential roles in the molecular design, which are reviewed in detail. In addition, some unusual liquid crystalline polymers are discussed. Chapter 4 is devoted to the phase identification of liquid crystalline polymers. The techniques involved cover polarizing microscopy, thermal analysis, X-ray diffraction, and other areas. Chapters 5 and 6 summarize the properties and applications of liquid crystalline polymers: Chapter 5 deals mainly with mechanical performance in fiber and composites; Chapter 6 presents the elasticity, viscosity and rheology of liquid crystalline polymers, as well as other important properties.

Liquid Crystals, Laptops and Life

Liquid Crystals, Laptops and Life connects the laptop computer with life itself via liquid crystals, the phases of matter essential to both. In the process it provides an integrated introduction to those parts of chemistry and physics that are necessary for understanding the basic science and technology embedded in the laptop and in life. This book can be understood by students with a good background in high school chemistry and physics; yet it can also serve as a primer for scientists who are not well versed in the areas covered.The first section of the book is devoted to discussion of basic concepts of chemistry and physics. The second section applies these concepts and extends them to three classes of materials that make the laptop possible: liquid crystals, polymers, and semiconductors. The first two classes of materials relate naturally to the molecules essential to life, thus providing an introduction to this area in an independent chapter. The third section focuses on the applied science and technology of semiconductors, digital devices, and computers, as well as liquid crystal displays. This section concludes by illustrating how these materials and technologies are combined in and make possible the laptop computer. The final section discusses applications of liquid crystals to the arts and to life. Each chapter rounds off with references to more advanced literature, exercises that test the reader's understanding, and open-ended questions that encourage the reader to explore the topics in greater depth.
