1 Critical Thickness and Dislocations The basic principle of strained-layer epitaxy is that a certain amount of elastic strain can be accommodated by any material without generating dislocations or defects. It takes energy to accommodate an epitaxial layer of lattice-mismatched material. During epitaxial growth the ﬁrst few layers are coherent with the matrix and the ﬁlm lattice suffers tetragonal distor-tion. As the ﬁlm thickness increases, dislocations begin to nucleate, and this partially relaxes the strain due to lattice mismatch and the thickness at which this occurs is desig-nated as the critical thickness (hc). It The epitaxial stabilization and transformation of cubic AlN layers in AlN/VN and AlN/TiN superlattices, grown by reactive sputtering on MgO ~001!, is described.

For many perovskite oxides, maximum thickness (critical thickness) that can be grown without phase separation was reported for In0.65Ga0.35N films by Pantha et al. [7] for the first time. They found that critical thickness was markedly increased with increasing growth rate, and interpreted such an 2018-07-02 Selective epitaxial growth of thin, high Ge-content, strained SiGe on oxide-patterned silicon was studied, specifically the effect of growth area on the critical thickness.

On the other hand, while some degree of intermixing occurs above the critical thickness, there is no evidence of formation of the YBCO phase. The novel solid-phase epitaxy observed below the critical thickness is believed to result from diffusion of species through grain boundaries of the initial precursor oxide layer, followed by reaction at the substrate interface to epitaxially nucleate the YBCO layers. 2018-07-02 · Combining the results from literature, three distinct growth categories were proposed by Rasic and Narayan: (i) non-epitaxial samples, (ii) epitaxial films grown on small misfit substrates (LME) and (iii) epitaxial films grown on large misfit substrates (DME) In the following, a summary of the critical considerations for epitaxy across the misfit scale in the presence of lattice/planar misfit, thermal and defect strains is presented. Perovskite-structured SrTi0.7Co0.3O3−δ (STCo) films of varying thicknesses were grown on SrTiO3(001) substrates using pulsed laser deposition. Thin films grow with a cube-on-cube epitaxy, but for films exceeding a critical thickness of about 120 nm, a double-epitaxial microstructure was observed, in which (110)-oriented crystals nucleated within the (001)-oriented STCo matrix, both Critical Thickness for Three-Dimensional Epitaxial Island Growth - Volume 130 - K.

The thickness of the epitaxial BaTiO 3 should be below its critical thickness. Epitaxial growth of metastable Pd(001) at high deposition temperatures up to a critical thickness of 6 monolayers on bcc-Fe(001) is reported, the critical thickness being depending dramatically on the deposition temperature.
