“…A prominent "domain-form" structure, found in epitaxial films of sphalerite structure CdS, CdSe and CdTe grown on (1 10) oriented surfaces of several cubic system substrates was shown, in the case of CdSe, to be due to the growth of polarity reversal domains, apparently arising by the wellknown epitaxial growth phenomenon of double position twinning [1]. Beautiful observations of polarity reversal domains in epitaxial GaAs and GaP grown on hemispherical germanium substrates and on silicon in several orientations were made by Morizane [15].…”

“…4. The polar octahedron is simpler than two polar tetrahedra [1] and can readily be constructed. The use of the term double position "twinning" for polarity reversal nucleation is unavoidable in relation to the terminology of epitaxial growth but is open to misinterpretation.…”

“…88 88 88 When slices of sphalerite-structure compounds are cut in {i 11} orientation, one side terminates in A atoms triply-bonded to the crystal. Such faces are termed (111) A surfaces and with the present sign convention [1], the (111)a directions are the outward normals to such faces. The other side of the slice terminates in B atoms triplybonded to the crystal.…”

The evidence for the occurrence of polarity reversal domains and inversion twins in compounds with the wurtzite and sphalerite structures is reviewed. Anti-coincidence lattices are defined for orientation relationships such that a fraction of sites of the two lattices coincide, but wrongly, to produce anti-coincidence sites. Proceeding from Friedel's theorem, the range of Friedel indices, 1, can be extended to unity and negative odd integers. Polarity reversal domains are characterised by / = --1 and n th order inversion twins by / = --(3) n. The partial symmetry operations producing coincidence and anticoincidence lattices are discussed.

“…6b) directions. Basing on such interpretation of satellite spots in diffraction patterns, Holt and coworkers investigated a wide number of II-VI thin epitaxial layers obtained on various substrates at wide range of substrate temperatures ( [33][34][35][36][37][38] see also review paper [10] and references therein). Palatnik [39,40] investigated nanocrystal layers consisting of CdTe particles grown on NaCl and KBr substrates.…”

defects in nanostructures seem to play crucial influence on their properties. Twinnings are the most popular 3D defects in II-VI semiconductor compounds having zinc-blende structure (Zn, Cd chalcogenides). These defects are of {111} type. Electron diffraction of such defected crystals as well as nanostructures (thin layers, clusters and other nanoscale individuals) results in satellite spots placed around the main single crystal spots in diffraction pattern. This is due to the different orientation of the matrix and twins of the first and higher orders with respect to the electron beam. Basing on a reciprocal lattice of twinned structure, the interpretation of nature of satellite spots is addressed. The double positioning, primary and double diffraction were described. The considerations were applied to the nanostructured epitaxial CdTe and Hg 1-x Cd x Te layers obtained by laser deposition.
