Infrared spectral emittance of InAs
D. L. Stierwalt, R. F. Potter
The infrared absorption spectra for a p-type InAs sample were determined by measuring the spectral emittance at 77, 203, and 373°K. The spectra contained features which are identified with optical edge transitions, free-carrier absorption, intervalence-band transitions, multiphonon absorption and the …

Thermal and optical energy gaps in PbTe
R. N. Tauber, A. A. Machonis, I. B. Cadoff
The optical absorption edge (indirect energy gap) for PbTe was determined in the temperature range of 80°-520°K. It was found that dEg/dT had a value of 4.1×10

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 …
