Electroluminescence II


Book Description

Since its inception in 1966, the series of numbered volumes known as Semiconductors and Semimetals has distinguished itself through the careful selection of well-known authors, editors, and contributors. The Willardson and Beer series, as it is widely known, has succeeded in producing numerous landmark volumes and chapters. Not only did many of these volumes make an impact at the time of their publication, but they continue to be well-cited years after their original release. Recently, Professor Eicke R. Weber of the University of California at Berkeley joined as a co-editor of the series. Professor Weber, a well-known expert in the field of semiconductor materials, will further contribute to continuing the series' tradition of publishing timely, highly relevant, and long-impacting volumes. Some of the recent volumes, such as Hydrogen in Semiconductors, Imperfections in III/V Materials, Epitaxial Microstructures, High-Speed Heterostructure Devices, Oxygen in Silicon, and others promise that this tradition will be maintained and even expanded.Reflecting the truly interdisciplinary nature of the field that the series covers, the volumes in Semiconductors and Semimetals have been and will continue to be of great interest to physicists, chemists, materials scientists, and device engineers in modern industry.

Hot Electrons in Semiconductors


Book Description

Under certain conditions electrons in a semiconductor become much hotter than the surrounding crystal lattice. When this happens, Ohm's Law breaks down: current no longer increases linearly with voltage and may even decrease. Hot electrons have long been a challenging problem in condensed matter physics and remain important in semiconductor research. Recent advances in technology have led to semiconductors with submicron dimensions, where electrons can be confined to two (quantum well), one (quantum wire), or zero (quantum dot) dimensions. In these devices small voltages heat electrons rapidly, inducing complex nonlinear behavior; the study of hot electrons is central to their further development. This book is the only comprehensive and up-to-date coverage of hot electrons. Intended for both established researchers and graduate students, it gives a complete account of the historical development of the subject, together with current research and future trends, and covers the physics of hot electrons in bulk and low-dimensional device technology. The contributions are from leading scientists in the field and are grouped broadly into five categories: introduction and overview; hot electron-phonon interactions and ultra-fast phenomena in bulk and two-dimensional structures; hot electrons in quantum wires and dots; hot electron tunneling and transport in superlattices; and novel devices based on hot electron transport.




Light-Emitting Diodes (3rd Edition, 2018)


Book Description

The 1st edition of the book “Light-Emitting Diodes” was published in 2003. The 2nd edition was published in 2006. The current 3rd edition of the book, a substantial expansion of the second edition, has 37 Chapters and includes a thorough discussion of white light-emitting diodes (LEDs), phosphor materials used in white LEDs, an expanded discussion of the various efficiencies encountered in the context of LEDs, and packaging materials and device technology. The background of light, color science, and human vision is provided as well. In the current edition, the fully colored illustrations are highly beneficial given the prominent role of light and color in the field of LEDs. The book is intended to be a comprehensive discussion of LEDs, particularly the physics, chemistry, and engineering associated with LEDs. It is published in electronic format in order to make the book affordable and easily accessible to a wide readership.




Light-Emitting Diodes (1st Edition, 2003)


Book Description

This book covers all aspects of the technology and physics of infrared, visible-spectrum, and white-light-emitting diodes (LEDs) made from III–V semiconductors. The book reviews elementary properties of LEDs such as the electrical and optical characteristics. The author also reviews advanced device physics including high-efficiency device designs, light extraction, radiative and non-radiative recombination dynamics, spontaneous recombination in resonant-cavity structures, and packaging. The reader is introduced to areas related to visible-spectrum and white LEDs such as human vision, photometry, colorimetry, and color rendering. Application of infrared and visible-spectrum LEDs in silica fiber, plastic fiber, and free-space communication is discussed. Extensive semiconductor material data, device design data, and analytic formulas governing the operation of LEDs are provided. Exercises and illustrative examples are used to reinforce the topics discussed. An introductory chapter reviews the historical developments and milestones of LED research and development. This textbook will be of interest to scientists and engineers working on LEDs, notably in lighting, illumination and signage, and also to graduate students in electrical engineering, applied physics, and materials science.




Mid-Infrared Coherent Sources and Applications


Book Description

Covering fundamental principles and the state of the art, this is a collection of reviews from experts in mid-infrared (mid-IR) coherent sources. Among the sources covered are optical parametric oscillators, difference frequency generators, and the most recent broadband crystalline, quantum cascade, and fiber lasers. The authors show how advances in mid-IR science and technology make these sources indispensable for a variety of applications.

Quantum Efficiency in Complex Systems


Book Description

Summary: Radiationless transfer of excitation energy is at the hear of many processes in quantum physics, chemistry and nanotechnology. Currently, the standard picture of an incoherent Förster resonant excitation transfer is being challenged by the experimental findings of a long-lived quantum mechanical coherence in biomolecular light harvesting complexes. The role of this in molecular aggregates is addressed in the first part of this volume. Utilizing some of the underlying principles to optimize nano scale devices, the second part addresses systems of colloid quantum dots and polymer based organic solar cells.
