    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1140 KB)

    A description is given of a newly discovered phenomenon which is observed when an electric field of a few thousand V cm−1 is applied to a homogeneous sample of n-type GaAs or InP. Above a well-defined threshold field, a time-dependent decrease in current is observed, which is largely independent of external circuit conditions. In long specimens this decrease is aperiodic, resembl... View full abstract»

  • Evaluation of Spectrochemical Data Using Digital Techniques

    Publication Year: 1964, Page(s):160 - 169
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (527 KB)

    This paper describes how a digital computer was used in combination with an emission spectrometer to determine chemical compositions of some steels. A mathematical model describing the relations between the composition and the intensities of the spectral lines was derived and experimentally tested. Both overlapping and matrix effects were considered. The computer was also used to calibrate the ins... View full abstract»

  • An Approach Towards Batch Fabricated Ferrite Memory Planes

    Publication Year: 1964, Page(s):170 - 176
    Cited by:  Papers (6)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (614 KB)

    This paper describes a technique for the batch fabrication of ferrite memory arrays in which wire, previously coated with a thermoplastic, is formed into two orthogonally disposed sets of parallel wires. These grids are oriented between opposing molds having matched grooves filled with a fluid mixture of ferrite powder and thermosetting resin, in such a manner that one set of parallel wires coinci...

    Following the original suggestion of R. W. Hellwarth,1 many investigators have succeeded in obtaining coherent light from optically pumped solid state lasers in the form of intense, sharp, single pulses. These pulses are commonly referred to as “giant” pulses, in recognition of the fact that their peak intensity far exceeds that of any of the several pulses (“spikes... View full abstract»

  • The Crystal Structure of CaPd3O4

    Publication Year: 1964, Page(s):185 - 186
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (257 KB)

    This paper describes experiments to determine the crystal structure of a new oxide of calcium and palladium, CaPd3O4. This compound was obtained during the course of efforts to prepare alkaline earth palladates. In this process excess CaCO3 was heated with PdO in air to about 800° to 900°C. At intervals the reaction mixture was removed from the furnac... View full abstract»

  • An Existence Theorem for the BCS Integral Equation

    Publication Year: 1964, Page(s):187 - 188
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (236 KB)

    An important consequence of the Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity is the existence of a gap in the energy spectrum. In the original BCS paper1 the gap function was found by solving a homogeneous nonlinear integral equation in which the phonon interaction energy was taken to be a constant in some appropriate region and to be zero everywhere else. In that case th... View full abstract»
