This year's nitride symposium showed the scope of nitride-related advances spanning basic materials physics over process technology to high-performance devices. Progress was reported in bulk growth of GaN and AlN, growth on various substrates and substrate orientations, optical properties of InN, defect and doping analysis of p-doped GaN, and polarization properties. These led to new performance records in visible light emitter technology, i.e., higher efficiency/higher brightness, UV emitters with shorter wavelength, and UV and photo detectors. Advances in the development of nitride-based electronic devices with new heterostructure FET designs for RF power applications, including those on Si substrates and wafer fusion, are also reported. This book captures the exciting developments in this rapidly progressing field. Topics include: epitaxy - devices and defect reduction; defects and characterization; epitaxy - nonpolar orientations and alloys; optical properties; UV emitters and detectors; visible light emitters; electronic devices; characterization of defects and transport; and contacts, processing and p-type nitrides.

This book from the Materials Research Society emphasizes the broad scientific and technological interest in applications of organic materials to optoelectronics and optics. Materials synthesis, modification, and characterization from the nanoscale to the mesoscale to the macroscale are discussed. Approaches for modeling and theoretical analysis of these materials are highlighted. Also featured in the volume are a keynote talk from Professor Alan Heeger, 2000 Nobel Prize winner in chemistry, as well as five papers from the Microphotonics symposium that address photonic crystals involving organic materials. Additional topics include: metal/organic interfaces - electronic structure and charge injection; photonic/nonlinear optical materials and devices; design and synthesis of electroluminescent materials; applications in displays; electrochromic polymers/sensors; organic transistors; photovoltaics and photodetectors - transport in bulk organic materials and novel patterning schemes.

This book provides a benchmark for the state of the field of thermoelectric materials research and development. Highlights of the volume include results on superlattices that show a ZT = 2.4 at room temperature in p-type Bi2Te3/Sb2Te3 superlattice thermoelectrics. In addition, preliminary results on p-n couple devices from these superlattices indicate fast-acting spot cooling in addition to improved performance. Thermoelectric materials are utilized in a wide variety of applications related to solid-state refrigeration or small-scale power generation. The book focuses on traditional thermoelectric materials new materials as well as developments in device engineering. Many papers presented here revolve around either maximizing the numerator of Z, called the power factor, or by minimizing l. Topics include: guidance to advanced thermoelectric research; skutterudites; new materials, approaches and measurements; clathrates; chalcogenides; devices; thermoelectric materials and devices - research and development; nanowires and oxides.
