Magnetron sputtering has been used to grow calcium fluoride films. The presence of calcium emission lines in the discharge and the absence of calcium fluoride lines indicate that deposition occurs largely atomically, rather than by molecules. Films g

We report on measurements of the effect of 18O-16O substitution on the superconducting properties of Y1Ba2Cu3O7−δ. Substitutions were made by gas-exchange alone, and by gas exchange in conjunction with substituted BaCO3 and CuO. From Raman scatter

A Mossabauer spectrometer based on a PDP-8L mini-computer has been designed and constructed. The computer supplies both the signal for the source motion and the data storage. The resulting spectrometer system has wide versatility of operation and dat

The lattice parameter of the diluted magnetic semiconductor Zn 1− x Mn x Te has been determined as a function of composition. This material crystallizes in the zinc-blende structure for values of x below about 0.75. The results show that for this r

We have analyzed the structural and optical properties of GaxIn1−xAs–GaAs strained-layer superlattices (SLS) grown by low-pressure metal-organic vapour-phase epitaxy. Sample uniformity over 2.5 cm × 2.5 cm has been studied by X-ray diffraction a

Nickel (001) surfaces were prepared by a combination of high temperature oxidation, argon ion bombardment and hydrogen reduction. The oxidation of this surface in pure C2 to form NiO was studied by reflection high energy electron diffraction (RHEED)
