This book from MRS dedicated to III-Nitrides, focuses on developments in AlN, GaN, InN and their alloys that are now finding application in short-wavelength lasers ( 400nm, cw at room temperature) and high-power electronics (2.8W/mm at GHz). Experts from fields including crystal growth, condensed matter theory, source chemistry, device processing and device design come together in the volume to address issues of both scientific and technological relevance. And while much of the book reports on advances in material preparation and the understanding of defect issues, similar advances in...

It is increasingly apparent that ion-beam-based processing offers unique capabilities for fabrication and complex patterning of 3D, 2D or 1D structures at the few-nanometer scale (e.g., nanowires and quantum dots), and for custom tailoring of nanocomposites, nanoporous materials, catalyst surfaces, optical materials and nanoparticle assemblies. This book addresses achievements, applications and insights into such areas. It also seeks to identify potential dimensional limitations to the future practical implementation of this approach. Topics include: ion-beam nanofab - tools, techniques and...

The scope of detector materials for semiconductors and scintillators includes a wide variety of molecular compounds such as cadmium zinc telluride (CZT), lanthanum halides, and others. An additional class of scintillators is based on organic compounds and glasses. Ideally, attributes of materials used for radiation detection include appropriate-range bandgaps, high atomic numbers of the central element, high densities, performance at room temperature, strong mechanical properties, and low production cost. Unfortunately, there are significant gaps in the knowledge required to produce radiation...
