Properties of the volume phase in the layerwise growth. Case of forming of new layer under effect of previous


State Scientific Institution "Institute for Single Crystals" of National Academy of Sciences of Ukraine, Nauky av. 60, 61001 Kharkov, Ukraine


It was studied in the work the properties of volume inclusions of transparent phase in an opaque sample, that grown layerwise. It was studied a case in which the regions of transparent phase of a new layer appear only above the regions of transparent phase of the previous layer. Numerical characteristics of this process - the average number <n> of "islands" of transparent phase in a new layer on one such "island" of previous layer. It was research the formation of regions of the transparent phase in separate layers and formation of through "windows of transparency" in the final sample. The law of changing of transparent phase area with the number of layer was received at different values of <n>. Mechanisms, that determine the form of different parts of the law was pointed. For final sample the distribution density of "windows" on area was obtained, analytically for separate exactly solvable case and numerically in the general case. It is shown that the density has three different parts, the properties of these parts was studied at different <n>. It was found the law of change of the total transparency of the sample with <n>.

Transparent phase, windows of transparency, total transparency of the sample.
