Optical measurements on the antiferromagnetic semiconductor MnTe
G. Zanmarchi
The light transmission and reflection of the antiferromagnetic semiconductor MnTe with Néel temperature TN = 307°K, have been measured for wavelengths ranging from the visible spectrum to 24 μ, and for different temperatures T from 80°K up to 375°K. The …

Reflectivity of tin telluride in the infrared
H. R. Riedl, J. R. Dixon, R. B. Schoolar
The reflectivity of tin telluride at near-normal incidence and room temperature was measured at wavelengths from 1 to 200. Thirteen single-crystal samples with free-hole concentrations ranging from 4.8×1019 cm-3 to 4.8×1020 cm-3 were studied. In the wavelength range from 3 …

ZnSb INTERMETALLIC COMPOUND: Normal spectral reflectance
Measurement and analysis of the infrared reflection spectrum of semiconducting SnS
C. Haas, M. M.g. Corbey
The infrared reflection spectrum of p-type SnS single crystals was measured between 2 and 25μ. The observed dispersion was ascribed to the combined effects of lattice vibrations and free holes. An analysis gave for the index of refraction n0 = …

Magnetic ordering effects on the reflectivity of EuS and EuSe
C. R. Pidgeon, J. Feinleib, W. J. Scouler, J. Hanus, J. O. Dimmock, T. B. Reed
The reflectivity of the ferromagnetic semiconductors EuS and EuSe has been measured as a function of temperature and polarization in a domain orienting magnetic field. The triplet structure below Tc and the doublet above are evidence that the absorption edge …

Optical Properties of Hexagonal ZnS Single Crystals
W. W. Piper, D. T.f. Marple, P. D. Johnson
The optical transmission of hexagonal zinc sulfide crystals has been measured in the spectral range from 0.32 to 15 μ. From the spacing of interference maxima, the dependence of index of refraction on wavelength has been determined. Measurements of the …

Optical Properties of Epitaxial PbS Films in the Energy Range 2-6 eV
C. E. Rossi, William Paul
The reflectivity of epitaxial PbS films has been compared with the reflectivity of bulk PbS in the energy range 2.1 to 6.2 eV and found to agree in both magnitude and structure within a few percent at energies where interference …

LEAD SULFIDE PbS: Normal spectral reflectance
The Reflectance of the Intermetallic Compounds NiAl and CoAl
D. A. Kiewit, J. O. Brittain, J. Rechtien
The reflectivities at normal incidence of samples of the intermetallic compounds NiAl and CoAl are presented in the photon energy region from 0.5 to 6.0 eV. The data and their interpretation are compared with those of Sambongi, Hagiwara and Yamadaya …

Electrical and structural properties of mixed chromium and silicon monoxide films
Alvin A. Milgram, Chih Shun LU
Films containing a mixture of chromium and silicon monoxide were prepared on glass substrates by vacuum deposition. The significance of various deposition parameters was determined. The films were examined by x-ray diffraction, electron microscopy, and ir reflectance and transmission. The …
