摘要:
AbstractMorphological stability is a complex problem, the clarification of which requires the simultaneous consideration of the natural transport of matter by diffusion and the surface incorporation kinetics, hence the distribution of concentration around the growing crystal (Seeger; Cahn; Chernov). In the present paper the instability of KBr single crystals due to the appearance of depressions on their faces during growth from aqueous solutions has been related with the actual concentration distribution on their surfaces and the directly measured growth rates.

摘要:
AbstractThe time τ for visible crystallization of NaPO3melts is measured in the whole range of undercoolings from the melting temperatureTmto the temperature of vitrificationTg. It is shown that the time τ, needed for the appearance of a visible crystallization at high supersaturations is determined by the linear growth rate, whereas the rate of heterogeneous nucleation is the main factor, determining the experimentally measured time τ at low supersaturations. The specific surface energy σ at the melt‐crystal interface is calculated from the data on nucleation velocity in the vicinity ofTmand the temperature dependences of both heterogeneous and homogeneous nucleation velocity for NaPO3melts are constructed. It is concluded that at normal cooling rates only nucleation, initiated by active crystallized cores could be observed for

摘要:
AbstractSingle crystals of the HgGaInS4layered compound were grown by the iodine transport technique. Results of their optical, photoelectric, and radiative properties' study are presented. The band gap and the binding energy of holes on the sensitizing centres were determined to beEg= 2.41 eV andEa= 0.2 eV, respectively. A presence of quasi‐continuously distributed states was stated which are responsible for the exponential segment of the absorption edge and which take part in the radiative recombinatio

摘要:
AbstractThe steady‐state temperature distribution of the growth system is calculated at various stages of the growth process. The results indicate a serious influence of the thermal transparency of the B2O3. The heater power which has to be adjusted in order to achieve a constant diameter growth is calculated as an inverse proble
