Available in PDF, EPUB and Kindle. Book excerpt: Polycrystalline platinum and palladium were bombarded with monoenergetic electrons at temperatures below 9K. Changes in electrical resistivity R(E) = delta rho/electron-sq cm were measured in the energy range 1.1 to 3.0 MeV. The experimental values found in this interval are consistent with displacement threshold energies of 37 eV for Pt and 34 eV for Pd. The resistivities per unit defect concentration were found to be 0.00075 and 0.0009 ohm-cm for Pt and Pd respectively. The threshold energies found here, together with values reported for other face centered cubic elements, are shown to be directly proportional to atomic number and inversely proportional to the lattice parameter. It is also shown that the resistivities per unit defect concentration can be correlated with the resistivity at 0C. Analysis of the energy dependence of the damage production indicates atomic displacement cascades are markedly inhibited, which is consistent with deuteron damage studies. Alternative multiple displacement models and possible mechanisms are discussed. (Author).

Download or read book Thermal Design of Electronic Equipment written by Ralph Remsburg and published by CRC Press. This book was released on 2017-12-19 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a field where change and growth is inevitable, new electronic packaging problems continually arise. Smaller, more powerful devices are prone to overheating, causing intermittent system failures, corrupted signals, lower MTBF, and outright system failure. Since convection cooling is the heat transfer path most engineers take to deal with thermal problems, it is appropriate to gain as much understanding about the underlying mechanisms of fluid motion as possible. Thermal Design of Electronic Equipment is the only book that specifically targets the formulas used by electronic packaging and thermal engineers. It presents heat transfer equations dealing with polyalphaolephin (PAO), silicone oils, perfluorocarbons, and silicate ester-based liquids. Instead of relying on theoretical expressions and text explanations, the author presents empirical formulas and practical techniques that allow you to quickly solve nearly any thermal engineering problem in electronic packaging.

Download or read book New Insulators Devices and Radiation Effects written by and published by Elsevier. This book was released on 1999-02-11 with total page 967 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon technology today forms the basis of a world-wide, multi-billion dollar component industry. The reason for this expansion can be found not only in the physical properties of silicon but also in the unique properties of the silicon-silicon dioxide interface. However, silicon devices are still subject to undesired electrical phenomena called "instabilities". These are due mostly to the imperfect nature of the insulators used, to the not-so-perfect silicon-insulator interface and to the generation of defects and ionization phenomena caused by radiation. The problem of instabilities is addressed in this volume, the third of this book series. Vol.3 updates and supplements the material presented in the previous two volumes, and devotes five chapters to the problems of radiation-matter and radiation-device interactions. The volume will aid circuit manufacturers and circuit users alike to relate unstable electrical parameters and characteristics to the presence of physical defects and impurities or to the radiation environment which caused them.
Download or read book Instrument for Radiation Testing Screening Electronic Devices Over an Extended Temperature Range written by L. J. Palkuti and published by . This book was released on 1986 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many military systems must be able to function over temperature ranges of -55C to 125C. Electronic devices within selected military systems must also be able to function in environments of long-term or high-intensity ionizing radiation. This program developed instrumentation and methodology that enables testing of electronic devices in such extreme conditions, using instrumentation compatible with the ARACOR Model 4100 Automatic Semiconductor Irradiation System. Instrumentation was developed to measure the integrated energy transmitted to an IC wafer die by a pulsed Nd:YAG laser beam. High and low temperature testing was found to be best achieved using a precision nitrogen gas forcing system. For Model 4100 Systems used for total-dose measurements, across the fall temperature range, a system combining a commercially-available, temperature-controlled chuck with an air stream was found to be best solution. For low temperature, high intensity radiation testing, temperature sensors on the wafer under test were found to be required for accurate temperature control. Keywords include: Electronic devices, Military systems, Temperature range, Ionizing radiation, Radiation testing and Radiation screening.

This book was released on 2004-07-29 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a detailed treatment of radiation effects in electronic devices, including effects at the material, device, and circuit levels. The emphasis is on transient effects caused by single ionizing particles (single-event effects and soft errors) and effects produced by the cumulative energy deposited by the radiation (total ionizing dose effects). Bipolar (Si and SiGe), metal-oxide-semiconductor (MOS), and compound semiconductor technologies are discussed. In addition to considering the specific issues associated with high-performance devices and technologies, the book includes the background material necessary for understanding radiation effects at a more general level.
