This book highlights state-of-the-art in III-nitrides-based light-emitting diodes (LEDs). Motivated by the application prospects in lighting, high-resolution display, and health & medicine, the book systematically introduces the physical fundamentals, epitaxial growth, and device fabrications of III-nitride-based LEDs. Important topics including the structures of chips, device reliability and measurements and the advances in mini and micro LEDs are also discussed. The book is completed with a decade of research experience of the author’s team in the design and fabrication of III-nitrides-based LEDs, presenting the novel achievements in the stress control of the large mismatch heterostructures, defect formation and inhibition mechanism of the heteroepitaxial growth, LED epitaxial technologies, and the fabrication of high-efficient flip-chip LEDs. The book comprises of a valuable reference source for researchers and professionals engaged in the research and development of III-nitrides-based LEDs.

Realization of the semiconductor laser diodes (LDs) operating in the blue wavelength region had been a 'dream' for a long time for the scientists working on widegap materials until just a few years ago. Quite remarkable progress has been made in the last few years the dream has come true. The first ZnSe-based blue/green LD was fabricated about four years ago and its officially reported life-time in CW operation exceeds 100 hours now; it is quickly approaching a practical use level. Further, GaN-based blue LDs have also been realized. In this way, the progress in these research fields is quite rapid. The work includes articles on bulk growth, epitaxy, doping and characterization, blue LDs and LEDs, and future prospects in both ZnSe-based and GaN-based areas.

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.
