Coincidence-site lattices are characterized mathematically, in the general case, by a method that can be applied to a pair of original lattices of any symmetry, either metrically identical or metrically different, does not involve inspection and is readily adaptable to computer calculations. The procedure is illustrat…
It is possible to set up equations of the formB(H) = a_{0} + a_{1} e^{-\alpha_{1}H} + a_{2} e^{-\alpha_{2}H} + a_{3} e^{-\alpha_{3}H} + a_{4} e^{-\alpha_{4}H}on an analog computer to fit accurately aB-Hcurve of any magnetic material over the whole range from zero to the knee of the curve to the saturation part of the…
Hall-effect measurements as a function of temperature have been made on single-crystal samples of V${\mathrm{O}}_{2}$ at temperatures both above and below the semiconductor-to-metal transition temperature; the Hall mobility in the semiconducting phase was approximately 0.5 ${\mathrm{cm}}^{2}$/V sec and in the metallic…

Abstract Azoverbindungen sind durch einen tiefliegenden 1(n,π*)‐Elektronenzustand charakterisiert, dem im Absorptionsspektrum eine langwellige, schwache Bande entspricht. Kopplungen dieses Zustands mit anderen tiefliegenden Molekülzuständen sind die Ursache der für verbotene Übergänge hohen Intensität, der Strukturlos…
Crystallographic notation for Al 2 O 3 is reviewed, with particular reference to the correct basis to be used in describing slip systems. A Groves‐and‐Kelly calculation showed that the combination of pyramidal slip on {11¯02}<11¯01> and basal slip on (0001){112¯0} will allow homogeneous deformation of Al 2 O 3 p…
In vacuum, the surface of insulators becomes electrically charged when subjected to high-voltage stresses. The charging mechanism is described. A model simulating the charging shows that the surface charge densities are proportional to the applied voltage and depend on the secondary electron emission of the dielectric…

This paper presents the results of our measurement of the room-temperature thermal conductivity of the Ga1−xAlxAs alloy system. The study was motivated by our need to characterize the thermal properties of cw heterostructure lasers, in which the heat generated in the optically active layer must flow through a substant…
