Описание: This book comes as a result of the research work developed in the framework of two large international projects: the European Science Foundation (ESF) supported program NATEMIS (Nonlinear Acoustic Techniques for Micro-Scale Damage Diagnostics) (of which Professor Delsanto was the European coordinator, 2000-2004) and a Los Alamos-based network headed by Dr. P.A. Johnson. The main topic of both programs and of this book is the description of the phenomenology, theory and applications of nonclassical Nonlinearity (NCNL). In fact NCNL techniques have been found in recent years to be extremely powerful (up to more than 1000 times with respect to the corresponding linear techniques) in a wide range of applications, including Elasticity, Material Characterization, Ultrasonics, Geophysics to Maintenance and Restoration of artifacts (paintings, stone buildings, etc.). The book is divided into three parts: Part I - defines and describes the concept of NCNL and its universality and reviews several fields to which it may apply; Part II - describes the phenomenology, theory, modelling and virtual experiments (simulations); Part III - discusses some of the most relevant experimental techniques and applications.

Описание: The development of nitride-based light-emitting diodes (LEDs) has led to advancements in high-brightness LED technology for solid-state lighting, handheld electronics, and advanced bioengineering applications. Nitride Semiconductor Light-Emitting Diodes (LEDs) reviews the fabrication, performance, and applications of this technology that encompass the state-of-the-art material and device development, and practical nitride-based LED design considerations. Part one reviews the fabrication of nitride semiconductor LEDs. Chapters cover molecular beam epitaxy (MBE) growth of nitride semiconductors, modern metalorganic chemical vapor deposition (MOCVD) techniques and the growth of nitride-based materials, and gallium nitride (GaN)-on-sapphire and GaN-on-silicon technologies for LEDs. Nanostructured, non-polar and semi-polar nitride-based LEDs, as well as phosphor-coated nitride LEDs, are also discussed. Part two covers the performance of nitride LEDs, including photonic crystal LEDs, surface plasmon enhanced LEDs, color tuneable LEDs, and LEDs based on quantum wells and quantum dots. Further chapters discuss the development of LED encapsulation technology and the fundamental efficiency droop issues in gallium indium nitride (GaInN) LEDs. Finally, part three highlights applications of nitride LEDs, including liquid crystal display (LCD) backlighting, infrared emitters, and automotive lighting. Nitride Semiconductor Light-Emitting Diodes (LEDs) is a technical resource for academics, physicists, materials scientists, electrical engineers, and those working in the lighting, consumer electronics, automotive, aviation, and communications sectors.

Описание:
The rapid growth of the use of optoelectronic technology in Information and Communications Technology (ICT) has seen a complementary increase in the performance of such technologies. As a result, optoelectronic technologies have replaced the technology of electronic interconnections. However, the control of manufacturing techniques for optoelectronic systems is more delicate than that of microelectronic technologies. This practical resource, divided into four chapters, examines several methods for determining the reliability of infrared LED devices. The primary interest of this book focuses on methods of extracting fundamental parameters from the electrical and optical characterization of specific zones in components. Failure mechanisms are identified based on measured performance before and after aging tests. Knowledge of failure mechanisms allows formulation of degradation laws, which in turn allow an accurate lifetime distribution for specific devices to be proposed.
Reliability Investigation of LED Devices for Public Light Applications focuses on state-of-the-art GaN-based LED technology through the study of typical failure mechanisms in public lighting applications.
Across the different chapters, the reader will explore the tools and analyses involved in the study and application of a number of different LED devices. The authors review GaN-based LED technology by focusing on the main failure mechanisms targeting polymer-based packaging, thanks to electrical and spectral models.
The proposed technology and methodologies will help those interested in the topic to further their knowledge of failure mechanisms, exploring the physical and chemical analyses involved.
Based on the work of two main Phd results in 2011 and 2014
Describes GaN technology in the state-of-the-art, focusing on the specific electrical and spectral model
Proposes the technology and methodologies to understand failure mechanisms
