Infrared lattice vibrational spectra of AgCl, AgBr, and AgI
G. L. Bottger, A. L. Geddes
The infrared transmission spectra of AgCl, AgBr, and AgI have been measured between 400-30 cm-1 at room temperature and at 143°K. Strong absorptions characteristic of the transverse optic modes were found, together with weak subsidiary absorptions arising from multiphonon combinations. …

Optical absorption in silicon monoxide
I. R. Rawlings
Measurements of the transmission spectra of thick silicon monoxide films are reported, and from these the absorption coefficient of silicon monoxide is calculated as a function of wavelength. The results obtained are compared with the predictions of a simple theoretical …

Current Saturation in the Evaporated GaAs Films
A. Yamashita, T. Tuzaki, T. Yamada, I. Yamauchi
Current saturation in evaporated GaAs films was observed. Thin GaAs films were fabricated by means of simultaneous evaporation of the elements of the highest purity onto the metal substrate of the Ta. Electrical characteristics of the films were measured employing …

Dielectric dispersion of some perovskite zirconates
C. H. Perry, D. J. Mccarthy, G. Rupprecht
The assignment of the normal-mode spectrum in perovskites has been achieved by a comparison of the vibrations of calcium, strontium, barium, and lead titanates and zirconates. In addition, for the antiferro-electric material lead zirconate, about 90% of the value of …

Optical properties and band structure of group IV-VI and group V materials
Manuel Cardona, D. L. Greenaway
Room-temperature reflectivity measurements over the energy range 0.5 to 25 eV have been made on the lead salts PbS, PbSe, PbTe, and on SnTe and GeTe; reflection curves have also been obtained for the structurally closely related Group V semimetals …

Infrared absorption of indium antimonide
Eugene Blount, Joseph Callaway, Morrel Cohen, William Dumke, James Phillips
Infrared absorption in InSb near the absorption edge has been interpreted as the superposition of two indirect transitions requiring phonons of 100°and 30°, the former transition involving the smaller electronic energy gap. The first transition is consistent with a band …

Reststrahl Reflection Characteristics of Amorphous Silica
Kenzo Sato, Miyoko Shibata
The Reststrahl reflection characteristics in the wavelength region 1-25µ of silica films, a few thousand ångstroms in thickness, have been studied. The films were grown on silicon wafers under controlled conditions. The reflection maxima in the Si-O stretching and Si-O …
