Sommario/riassunto

In this book, leading experts on quantum dot theory and technology provide comprehensive reviews of all aspects of quantum dot systems. The following topics are covered: (1) energy states in quantum dots, including the effects of strain and many-body effects; (2) self-assembly and self-ordering of quantum dots in semiconductor systems; (3) growth, structures, and optical properties of III-nitride quantum dots; (4) quantum dot lasers. <br><i>Contents: </i><ul><li>Low-Dimensional Systems <i>(E Borovitskaya & M S Shur)</i></li><li>Energy States in Quantum Dots <i>(A J Williamson)</i></li><li>Sel
