Opis:: This paper considers an analytical approach for the prognosis of mass and heat transport during the growth of epitaxial layers by means of pulsed laser deposition. The approach provides the opportunity to make a prognosis which takes into account the spatial and temporal variations of their parameters and, at the same time, the nonlinearity of these processes. Based on this approach, the influence of the variation of several parameters on the growth process is investigated.

Tematy:: gas phase epitaxy
improvement of properties of films
analytical approach for modeling
Opis:: In this paper, the effect of the preliminary processing of a substrate on the properties of a grown heterostructure is investigated. It is shown that the growth of an epitaxial layer on a buffer layer after preliminary annealing (before the growth) makes it possible to decrease the value of mismatch-induced stress. An analytical approach has been introduced for the analysis of mass and heat transfer in a multilayer structure accounting for mismatch-induced stress.

Tytuł:: A model for changing the technological process for the growth of epitaxial layers by means of the heating of the growth zone

Opis:: The nonstationary transfer of heat during epitaxial layer growth in gas phase epitaxy reactors is analyzed within the work. Based on this analysis, several recommendations on the organization of the heating of the growth zone to increase the homogeneity of the epitaxial layers were formulated. An approach to analyze the transfer of heat during epitaxial layer growth from the gas phase is also introduced. The approach leads to the possibility of simultaneously accounting for heat transfer nonlinearity and changes of parameters of heat transfer in both space and time.

Opis:: An approach to decreasing mismatch-induced stress in a heterostructure by radiation processing during growth from the gas phase is introduced in this paper. Within the framework of the approach with decreasing mismatch-induced stresses, one can find the acceleration of the recombination and diffusion of radiation defects generated during radiation processing. An analytical approach for analyzing mass and heat transfer is also introduced. The approach provides the opportunity to simultaneously take into account spatial and temporal variations of mass transfer parameters. At the same time, the approach allows the nonlinearity of the considered processes to be taken into account.

Tytuł:: On the method of changing the temperature of liquids and gases in a transportation system by local heating or cooling

Tematy:: liquids and gases transport

Opis:: In this paper we consider an approach of changing the temperature of liquids and gases in a pipeline by local heating and cooling. The approach based on changing of temperature of series sections of the pipeline due to external modification of temper-ature of these sections. This situation could be used for heat sink or increasing of temperature. A model of heat transfer based on transfer of heat in a pipeline with account convection due to liquid/gas transport has been introduced. We also introduce an ana-lytical approach for analysis of liquid/gas transport with account transport of heat due to convection. The approach gives a possi-bility to take into account spatial and temporal variation of parameters of transport and at the same time to take into account non-linearity of considered processes.
