This work provides and highlights the effects of microscopic ordering on the properties of semiconductor alloys. It brings us one-step closer in understanding the fundamental ground that influences the properties of semiconductor alloys. For the alloy studied, i.e. AlGaAs, GaInP, BGaP, and AlGaInP, our results can serve as a guide for theoreticians, experimentalists, and device engineers to focus on the microscopic structures that are predicted to give their desired properties. This work will draw attentions to the fact that properties of semiconductor alloys can be adjusted by controlling the atomic ordering in addition to the alloy composition. This opens up a new way to control semiconductor properties, such as bandgap and electron effective mass. This work also helps to gain better understanding in the relationship between atomic arrangements in alloys and the observable properties.

The phenomenonofspontaneous ordering in semiconductoralloys, which can be categorized as a self-organized process, is observed to occur sponta neously during epitaxial growth of certain ternary alloy semiconductors and results in a modification of their structural, electronic, and optical properties. There has been a great dealofinterest in learning how to control this phenome non so that it may be used for tailoring desirable electronic and optical properties. There has been even greater interest in exploiting the phenomenon for its unique ability in providing an experimental environment of controlled alloy statistical fluctuations. As such, itimpacts areasofsemiconductorscience and technology related to the materials science ofepitaxial growth, statistical mechanics, and electronic structure of alloys and electronic and photonic devices. During the past two decades, significant progress has been made toward understanding the mechanisms that drive this phenomenon and the changes in physical properties that result from it. A variety of experimental techniques have been used to probe the phenomenon and several attempts made atproviding theoretical models both for the ordering mechanisms as well as electronic structure changes. The various chapters of this book provide a detailed account of these efforts during the past decade. The first chapter provides an elaborate account of the phenomenon, with an excellent perspective of the structural and elec tronic modifications itinduces.
