Interpretation of the vacancy-ordering controlled growth morphology of Hg5In2Te8 precipitates in Hg3In2Te6 single crystals by TEM observation and crystallographic calculation

Formation and characterization of a CuPt-A type ordered structure in cadmium zinc telluride single crystals

“…Such contrast can be attributed to the stress field generated by the lattice mismatch between the ordered phase and the matrix, which also indicates the approximate position of the ordered phase in the figure. The collected SAED patterns exhibit the typical features of local ordering with the hexagon shaped rings, which have been observed in other II–VI group semiconductor single crystals with ordered phases, 43,44 as shown in Fig. 2(e).…”

An atomic scale structural investigation of nanometre-sized η precipitates in the 7050 aluminium alloy

“…The structure of Mg4Zn7 [51,52,54] supposedly involves with the formation or annihilation of vacancies and dislocations, leading to the change of lattice constants to accommodate the variation of interface energy [44], which would presumably be consistent with the alternations of the stacking sequences in the Laves phases, proposed by Komura et al [26]. Alternatively, in the present work, vacancies and dislocations can be introduced by the layer-by-layer growth or coalescence of η crystals, changing both the atomic spacing and the electronic state between Zn and Mg solute atoms [21].…”

“…Therefore, the lower lattice misfit, dominating the lower interfacial energy during the growth of precipitates, should be considered a significant factor in the selected growth direction, for it leads to a different morphology [41,42]. The related viewpoint can be seen in previous investigations illuminating the growth morphology of precipitates [7,34,43,44]. By considering the lattice-mismatch factor, it can be found that the morphology of η' (or η2) will eventually develop into the plate-like shape.…”

Diverse Interface Structures in TiO2 (B)/Anatase Dual‐Phase Nanofibers

“…Based on the 3D invariant line theory, the IDE model has been proved to be a powerful tool to predict and interpret the interfaces crystallography in various crystal systems . According to such model, the HP in a certain phase transition should contain a Burgers vector of the parent phase.…”

“…These models include invariant line strain (ILS) model, O‐lattice model, Edge‐to‐Edge matching model, fundamental building block (FBB) model, and invariant deformation element (IDE) model . Among all the above mentioned calculation methods, the IDE model has been widely applied on various materials systems due to the simplified calculation process and strong universality . The establishment of the initial lattice correspondence is normally the first step to start an ILS based crystallographic calculation.…”
