Progress In Semiconductor Materials For Optoelectronic Applications Volume 692

The MRS Symposium Proceeding series is an internationally recognised reference suitable for researchers and practitioners.

Recent years have witnessed dramatic success in the development of semiconductor materials and related quantum structures for applications in electronics and optoelectronics. Progress has also been made in manufacturable (low cost, high volume) growth and processing of semiconductor materials for such device structures. Novel approaches have been proposed to integrate compound semiconductor devices with conventional silicon processing. This book provides a comprehensive overview of the progress on growth, properties and processing of semiconductor materials and quantum structures, as well to underscore the progress on devices such as transistors, light sources, detectors and modulators. Brought to maturity, these devices will likely see widespread application in infrared imaging, chemical and biological sensing, surveillance, short links, space-based applications, solar cells, high-bandwidth communications, and more. Topics include: electronic devices; Si/Ge devices and technology; zinc oxide and related compounds; emitters, lasers and photovoltaics; nanostructures; innovative materials and devices; detectors; and III-nitride materials and devices.

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.

Central to bandgap engineering, or more precisely, 'wave-function engineering,' is the concept that, by spatially varying the composition and doping of semiconductors over distances ranging from a few micrometers down to one monolayer, one can tailor the electronic band structure in a nearly arbitrary and continuous way using epitaxial growth techniques. The objective of this book is to review the progress on interband and intersubband transitions in semiconductors including III-V, IV and II-VI materials and quantum structures, as well as to cover the progress on light sources, detectors, modulators and electronic materials and devices. This book brings together internationally recognized researchers to report on their most recent results and newly gained insights and to provide an up-to-date snapshot of optoelectronics and related fields in 2004/2005. The book covers a wide range of topics spanning opto- and microelectronic materials, growth and synthesis, devices, experimental techniques, modeling tools, and applications. Wavelength ranges span from the UV to the THz, and into the GHz modulation range.

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.

Recent developments in semiconductor materials and quantum structures are leading to significant advances in optoelectronic devices such as mid-infrared lasers and light-emitting diodes; long-wavelength detectors and solar cells; and modulators and optical switches. This book highlights the progress in both naturally- and artificially-structured 'wave-function-engineered' semiconductors, focusing on epitaxial compound-semiconductor compounds and alloys. The relationships among electronic, optical, and transport properties are emphasized, as are the implications for design and performance. Materials of particular interest include the familiar III-V compounds and alloys; newer offspring of these, such as the dilute-nitride III-Vs; ZnO and II-IV semiconductors; and spintronic materials. Exploratory studies of less commonly studied materials which may be of increasing future interest are also featured. Topics include: low bandgap and dilute-nitride semiconductors; growth, structure and defects; emitters, detectors and solar cells; devices; zinc oxide; spintronics and quantum structures; quantum dots and wires-structure, spectroscopy and transport and quantum dots and wires-devices.
