Revised and fully updated, the Second Edition of this textbook offers a comprehensive

explanation of the technology and physics of light-emitting diodes (LEDs) such as infrared,

visible-spectrum, ultraviolet, and white LEDs made from III–V semiconductors. The

elementary properties of LEDs such as electrical and optical characteristics are reviewed,

followed by the analysis of advanced device structures.

With nine additional chapters, the treatment of LEDs has been vastly expanded, including

new material on device packaging, reflectors, UV LEDs, III–V nitride materials, solid-state

sources for illumination applications, and junction temperature. Radiative and non-radiative

recombination dynamics, methods for improving light extraction, high-efficiency and highpower

device designs, white-light emitters with wavelength-converting phosphor materials,

optical reflectors, and spontaneous recombination in resonant-cavity structures, are discussed

in detail. Fields related to solid-state lighting such as human vision, photometry,

colorimetry, and color rendering are covered beyond the introductory level provided in the

first edition. The applications of infrared and visible-spectrum LEDs in silica fiber, plastic

fiber, and free-space communication are also discussed. Semiconductor material data,

device design data, and analytic formulae governing LED operation are provided.

With exercises, solutions and illustrative examples, this textbook will be of interest to

scientists and engineersworking on LEDs, and to graduate students in electrical engineering,

applied physics, and materials science.
