After two introductory chapters supplying basic background, chapters describe recent developments in materials and devices for red, amber, blue, and green light emitting diodes (LEDs). A final chapter discusses applications in detail. Specific topics are AlGaAs red LEDs, OMVPE growth of AlGaInP for high-efficiency visible LEDs, organometallic vapor-phase epitaxy of gallium nitride for high-brightness blue LEDs, and Group II-V nitride-based ultraviolet blue-green-yellow LEDs and laser diodes. Can be used as a stand-alone text for graduate courses or as a reference for engineers and scientists. Annotation c. by Book News, Inc., Portland, Or.
Volume 48 in the Semiconductors and Semimetals series discusses the physics and chemistry of electronic materials, a subject of growing practical importance in the semiconductor devices industry. The contributors discuss the current state of knowledge and provide insight into future developments of this important field.

Stringfellow was among the pioneers of the organometallic vapor phase epitaxial (OMVPE) growth technique, beginning his work in this area in 1975. He has published over 150 papers on this subject and delivered 30 invited papers at national and international conferences during the last 5 years. This work emphasizes the materials science aspects of OMVPE growth, including the thermodynamic and kinetic aspects of the process, the development of new source materials, and the growth of metastable alloys. The first epitaxial layers of InAsSb in the range of solid immiscibility. InPSb, GaPSb, GaInPSb, GaInAsSb, InAsBi, InSbBi, and InAsSbBi, inside the miscibility gap, were produced in Stringfellow s group. The growth of immiscible alloys has led to the discovery of atomic scale ordering in many III/V alloys. He and his students recently demonstrated the control of domain size in these ordered materials by using grooves photolithographically produced on the (001) surface. This had resulted in the largest ordered domains ever produced in semiconductor materials. Current research focuses on the ordering mechanism, particularly the effects of surface structure on ordering.Other important work is involved with the development of new procedures for OMVPE. He and his students pioneered the now widely-used tertiarybutylarsine and tertiarybutylphosphine. They also used several other precursors for the first time, including: ethyldimethylindium, triisopropylantimony, triallylantimony, trivinylantimony, and tertiarybutyldimethylantimony.
