    Notes: [Auszug] Introduction DURING the past four or five years a considerable effort has been made, notably in the United States and the United Kingdom, to gain precise information on the world-wide distribution of radioactive fallout from nuclear weapon tests. Results of such measurements to about mid-1957 were ...

    Notes: [Auszug] Between July 1 and December 31, 1960, 361 specimens of human bone tissue were collected in the five capital cities and compounded for analysis according to the methods discussed previously2. A comparison of the present results with those from previous periods shows that the levels of strontium-90, ...

    Time delays in lead-salt semiconductor diode lasers (1984)
    Springer
    Applied physics 33 (1984), S. 181-182 
    Details
    ISSN: 1432-0630
    Keywords: 42.80

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Abstract Time delays of typically 15–17μ have been measured directly for PbS1−xSex, Pb1−xSnxSe and Pb1−xSnxTe diode lasers at injection levels just above threshold in each case. The corresponding minority carrier lifetimes, as determined using the one-carrier injection model, were typically 2–4μ.

    Notes: [Auszug] EARLY in 1956 a network of stations established by the Atomic Weapons Tests Safety Committee commenced to monitor radioactivity in fall-out over Australia from weapon tests at the Monte Bello Islands and at Maralinga, as well as from those held overseas1-7. The number of stations operative, as well ...

    Vapour-deposited CdS films and their dependence on the source material (1987)
    Springer
    Journal of materials science 22 (1987), S. 3745-3748 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract An investigation has been made of the conditions required for the formation of vapour-deposited CdS thin films with reproducible characteristics suitable for use in photovoltaic solar cells. Cathodoluminescence spectroscopy has been used to provide information on differences in composition between the deposited films and the source material from which they were produced, and particular consideration has been given to the influence of the source material structure and stoichiometry on the electrical properties of the resultant films. Under identical deposition conditions, four different high-purity sources were shown to produce films with very different electrical characteristics, but by selecting appropriate deposition conditions (substrate temperature and deposition rate) it was found that each material was capable of generating films with the required characteristics.

    Blue light emitting ZnS diodes (1986)
    Springer
    Journal of materials science 21 (1986), S. 3227-3230 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Low resistivity n-type ZnS single crystals of about 103Ω cm and 102Ω cm were achieved by firing the as-grown high resistivity ZnS single crystals using quartz ampoules and graphite crucible, respectively. Schottky diodes fabricated from sample I gave stable blue emission in reverse bias while sample II gave blue emission in forward bias. The characteristics of these diodes were studied and presented. Carrier concentrations were estimated from the capacitance-voltage measurements of the two types of diodes. Electroluminescence spectra as well as cathodoluminescence spectra of both samples are presented. The blue emission peak was ascribed to the donor-acceptor pairs transition.
