    Photoacoustic infrared spectroscopy of some solids (1981)
    Springer
    International journal of infrared and millimeter waves 2 (1981), S. 23-34

    ISSN: 1572-9559
    Keywords: photoacoustic spectroscopy ; infrared spectroscopy ; semiconductors ; ionic powders

    Topics: Physics
    Notes: Abstract Infrared spectra in the 100–15000 wavenumber region (0.67–100 μm) of some ionic (as LiF) and semiconducting (as Ge, Si, GaAs) powders and crystals are reported. The experiment involves the use of a photoacoustic cell as an accessory to a multiple scan averaging Michelson interferometer. The results show the advantages of studying impurities in powders, and surface properties, particularly since the technique is immune to scattering induced errors.

    The far infrared complex reflectivity of GaTe (1980)
    Springer
    International journal of infrared and millimeter waves 1 (1980), S. 309-317 
    Details
    ISSN: 1572-9559
    Keywords: far-infared spectroscopy ; amplitude-phase ; optical properties ; semiconducting GaTe
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The room temperature polarized complex (amplitude and phase) infra-red reflection spectra of single crystal monoclinic GaTe have been measured between 20 and 400 cm−1 using a dispersive Fourier transform spectrometer. The measurements allow the experimental zone centre transverse and longitudinal phonon modes and optical constants to be determined without recourse to oscillator fit models or Kramers-Kronig analysis. Infrared power transmission measurements have allowed all fifteen predicted modes to be identified and the results are compared to recent Raman work.

    The temperature dependence of the raman effect in some wurtzite type crystals (1977)
    Chichester [u.a.] : Wiley-Blackwell
    Journal of Raman Spectroscopy 6 (1977), S. 123-129 
    Details
    ISSN: 0377-0486
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology , Physics
    Notes: The temperature dependence of the one phonon Raman spectra of ZnS (hex.), ZnO and a-Sic crystals is studied over the temperature range 15 to 1000 K. For ZnS frequency shifts are calculated by Griineisen theory and the k = 0 longitudinal and transverse optic phonon Griineisen parameters determined. The results are compa, indicating that the principal interactions are the cubic anharmonicities. Various calculated properties include the area, second moment, and simulated Raman bands to illustrate the anharmonic behaviour in the solids.
