Available in PDF, EPUB and Kindle. Book excerpt: This research has been conducted in order to address the absence of effective solid-state ultraviolet (UV) detectors and imagers. Despite the wide range of advances in visible and infrared imagery, until recently there have been no semiconductor devices under development for imaging strictly in the ultraviolet region of the spectrum. Much of the difficulty in creating such devices has been due to the lack of appropriate materials; however, the development of the group III-nitrides (III-N), including materials such as GaN and AlGaN, has provided a solution to this dilemma. The AlxGa1-xN based devices synthesized during this research were grown via organo-metallic vapor phase epitaxy and processed using standard photolithography, e-beam evaporation, and reactive ion etching processes. Focal plane arrays were subsequently bump bonded to silicon read-out integrated circuits (ROICs), which were then wire bonded to 84-pin leadless chip carriers. A specialized video camera and focal plane array evaluation software were used to test the imagers. The devices exhibit very low noise and very high sensitivity to ultraviolet radiation. Excellent quality UV images have been obtained for both 128x128 and 320x256 large format hybridized focal plane arrays. These new devices may find widespread usage in a number of applications that require sensitive UV detectors and UV imagers but where the cost, size, and power requirements of a photomultiplier tube cannot be justified.

Available in PDF, EPUB and Kindle. Book excerpt: The Department of Defense recently highlighted intelligence, surveillance, and reconnaissance (ISR) capabilities as a top priority for U.S. warfighters. Contributions provided by ISR assets in the operational theaters in Iraq and Afghanistan have been widely documented in press reporting. While the United States continues to increase investments in ISR capabilities, other nations not friendly to the United States will continue to seek countermeasures to U.S. capabilities. The Technology Warning Division of the Defense Intelligence Agency's (DIA) Defense Warning Office (DWO) has the critical responsibility, in collaborations with other components of the intelligence community (IC), for providing U.S. policymakers insight into technological developments that may impact future U.S. warfighting capabilities. To this end, the IC requested that the National Research Council (NRC) investigate and report on key visible and infrared detector technologies, with potential military utility, that are likely to be developed in the next 10-15 years. This study is the eighth in a series sponsored by the DWO and executed under the auspices of the NRC TIGER (Technology Insight-Gauge, Evaluate, and Review) Standing Committee.

Book excerpt: This report includes work on two types of two-dimensional position-sensitive detectors that were developed in this lab under this award. We worked to develop and optimize the wire-wound helical delay line detector (HDL) in the first and second years. Some early work on the HDL is contained in a paper included as Appendix A. In the second and third years we developed the concept for, then successfully designed and tested, both a lab prototype, and a flight prototype of the first, crossed delay line detector based on two orthogonal serpentine delay lines (SDL). Some of the work on the SDL is contained in a paper included as Appendix B. Appendix C contains copies of the invention report and record. Martin, Christopher Unspecified Center NAGW-2593...

This book was released on 2006-02-24 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semiconductor spintronics is expected to lead to a new generation of transistors, lasers and integrated magnetic sensors that can be used to create ultra-low power, high speed memory, logic and photonic devices. Useful spintronic devices will need materials with practical magnetic ordering temperatures and current research points to gallium and aluminium nitride magnetic superconductors as having great potential. This book details current research into the properties of III-nitride semiconductors and their usefulness in novel devices such as spin-polarized light emitters, spin field effect transistors, integrated sensors and high temperature electronics. Written by three leading researchers in nitride semiconductors, the book provides an excellent introduction to gallium nitride technology and will be of interest to all reseachers and industrial practitioners wishing to keep up to date with developments that may lead to the next generation of transistors, lasers and integrated magnetic sensors.
