By examining passivated silicon integrated circuits in the scanning electron microscope, the surface contours of p‐n junctions have been mapped, potential drops across integrated resistors have been observed, and physical characteristics of the oxide surface, evaporated leads, and bonded gold wires have been determine…
Abstract Radiation annealing is considered for the particular case of spontaneous recombination of a vacancy and an interstitial which lie closer together than a certain critical distance. By employing a simplified statistical method, a generalized theoretical dose curve is obtained. The theoretical results are applie…
The influence of the particle factor and lattice factor on the positions of the small-angle reflections of polymer crystalline samples is investigated. Since a single-crystal cake or a polymer solid crystallized from melt supposedly consists of stacks of nearly parallel plate-like lamellae, one may describe the scatte…
Abstract Die Infrarotspektren von 25 Sulfaten und Phosphaten bekannter Kristallstruktur wurden aufgenommen. Die Auswahlregeln der site‐Symmetrie werden befolgt gefunden mit Ausnahme von K‐, Rb‐ und Cs‐Verbindungen und im Gegensatz zu vollständig hydratisierten Salzen. Zusätzliche Korrelationsfeldaufspaltung wird beoba…

A simple nondestructive method of measuring the refractive index and thickness of transparent films on reflective substrates has been developed. The technique involves the use of a microscope equipped with a monochromatic filter on the objective and a stage that can be rotated so that the reflected light is observed a…

Electron microscopy has been employed to investigate the structures of various face-centered cubic solid solutions, particularly austenitic alloys, which are susceptible and nonsusceptible to transgranular stress corrosion cracking. It has been found that susceptibility is associated with those alloys in which disloca…

Following the previous reports on borate and silicate systems, we studied the glass-formation range of germanate systems. Germanate glass has a structure similar to that of silicate However, these systems have not been sufficiently studied and practically utilized, because germanium is a rare element. The molecular we…
Abstract
Radiative corrections to the electron scattering from nucleons and nuclei at high energies (> 50 MeV) are considered. Many formulas in the MO and Tsai’s article in-Review of Modern Physics are improved--rc-- *. and better derivations of them are presented. The effects of the strag-gling of electrons in the medi…

Abstract Differential thermal analysis and thermogravimetric analysis were used to evaluate the thermal properties of several types of polyurethane elastomers. The composition of the polymers investigated was changed by varying the substrate, or soft segment, diisocyanate and extender. The data indicated that within t…

The heating effect of an electron beam, under the assumption that the entire beam energy is imparted to the target surface (disc heating model), can be calculated fairly readily. At the high voltages and small beam diameters employed in electron-beam machining, however, the problem is complicated by penetration of ele…
