Book Description
The Structural and electrical changes caused by the implantation and annealing of donor and acceptor ions into Hg1-xCdxTe (x=0.2-0.3) were studied by a variety of ion-beam probing (RBS or PIXE combined with channeling) and electrical (C-V, Hall, photodiodes) techniques. Several annealing procedures (Furnace, Q switched Ruby laser and CW CO2 laser) were tried. Best annealing was obtained when the implanted HgCdTe was heated for 0.4 seconds to 380 deg C by exposing it to a flash of photons delivered by a CW CO2 laser. This novel mode of Rapid Thermal Annealing is shown to recover the crystal structure without causing changes in stoichiometry and to electrically activate both donor (B) and acceptor (P) implants Mesa and planar p on n photodiodes, sensitive to IR radiation (3.5-5 micrometers, were obtained when this annealing procedure was employed to P implanted (200KeV, 2X10 to the 14th power/sq.cm) n-Hg. 71Cd. 29Te. Originator supplied keywords include: Ion implantation, Laser annealing, HgCdTe, Radiation damage, Defects in semiconductors.

Book Description
This new edition of Infrared and Terahertz Detectors provides a comprehensive overview of infrared and terahertz detector technology, from fundamental science to materials and fabrication techniques. It contains a complete overhaul of the contents including several new chapters and a new section on terahertz detectors and systems. It includes a new tutorial introduction to technical aspects that are fundamental for basic understanding. The other dedicated sections focus on thermal detectors, photon detectors, and focal plane arrays.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
