Light-Emitting Diodes

Revised and fully updated the second edition of this graduate textbook offers a comprehensive explanation of the technology and physics of LEDs such as infrared visible-spectrum ultraviolet and white LEDs made from III-V semiconductors. Elementary properties 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 high-power device designs white-light emitters with wavelength-converting phosphor materials optical reflectors and spontaneous recombination in resonant-cavity structures are discussed in detail. With exercises solutions and illustrative examples this textbook will be of interest to scientists and engineers working on LEDs and graduate students in electrical engineering applied physics and materials science.
