“…4 in a diffraction pattern from a (100) film tilted so that the electron beam was incident in a (110) direction. Microdensitometer traces confirmed that there were no intensity maxima, due to microtwins or wurtzite grains [3][4][5], along the streaks.…”

“…These grains all occur with the (0001) basal plane parallel to the (100) plane of the cubic matrix of the film. The (1 1 I) from the cubic matrix spots are to be expected when microtwins and grains of hexagonal material occur on the {11 1 } planes of the cubic matrix [3][4][5]. However none of these satellite spots, ascribable to microtwins or to wurtzite in orientations other than the doublypositioned ones, were ever observed, nor were included grains, other than doubly-positioned wurtzite, ever seen.…”

The defect structures of epitaxial films of ZnS evaporated onto NaCI in vacuum were studied by transmission electron microscopy. Included grains of doubly-positioned wurtzite-structure material were found in many of the monocrystalline sphalerite-structure films. No twins or wurtzite grains in other orientations were ever observed.Numerous {111} planar defects were present in the films that were grown free of included grains. Interaction between doubly diffracted electron beams, arising from the (11 1) streaks due to the planar defects and the direct beam produced characteristic systems of fine-scale fringes and dots which dominated the appearance of the micrographs. Annealing in vacuum and in H2S failed to eliminate the planar defects.

“…The rather small fault density parameters ( 0.015 and 0.06) are insufficient to ensure formation of an extra reflection. Another independent argument against the assumption under discussion is the presence of the d 2 peak, which does not appear due to boundary diffraction [18].…”

The transmission high electron energy diffraction (THEED) technique was employed for studying the structure of the equimolar Ar-Kr alloy, in which the thermodynamics predicts the maximum feasibility of phase separation. Deposition of preliminarily cooled gas mixtures was performed onto substrates cooled to 6 or 20 K. All diffraction patterns contained several sets of reflections against an appreciable background. Analysis of the data obtained during a warm-up from 6 to 33 K (at which the major part of argon was removed due to sublimation) as well as of the diffraction pattern from the "sandwich" (two successively deposited film of pure Ar and Kr) provided reliable arguments for the following conclusions. Actually, we have documented for the first time a phase separation of an Ar-Kr mixture, manifestations of which turned out to be oddly asymmetric as far as the behavior of the components involved is concerned. Upon deposition both onto 6 or 20 K the emerging sample contained two crystal phases of virtually pure argon with a small admixture of krypton. One of the Ar phases (fcc) did not cause a surprise, whereas the other was hcp with the a/c ratio close to the ideal value. The krypton component separated as a fine-grained glass-like state, possibly, with a low admixture of argon.

“…metals grown epitaxially on a variety of substrates contain large numbers of microtwins on (111) planes (for a review see Pashley (1965)). Previous studies of defect structures in such deposits have been concerned mainly with the relatively early stages of growth, that is with films of thickness up to about 1000 11.…”
