Determination of the degree of ordering of materials’ structure by calculating the information-correlation characteristics

“…As was shown previously [2], the surface of a grown material is equal to a "frozen" simultaneous representation of the growth processes. Consequently, the degree of repro ducibility of the parameters of solid materials can be estimated using correlations in the structure of its sur face.…”

“…These properties manifest themselves in the form of correlations; i.e., interrelations between dis tant parts of the system are formed and sustained. Therefore, in combination with the Tuckens method, we used mathematical methods (in particular, infor mation theory) to reveal long range correlations as the main indication of the presence of self organization in the process of material synthesis [2].…”

Research on Amorphous Silicon Thin-Film Structure and Growth Processes Using Nonlinear Dynamics Methods

“…Taking into consideration that the processes of growth pass through a stage of the spatial -temporal determined chaos, it is possible to use methods applied to managing nonlinear chaotic systems [5]. There should be exercised different approaches to management based on the awareness of these processes.…”

“…In the case when it is necessary to obtain an ordered crystal structure, the well-known method of stabilizing unstable orbits of the chaotic attractor proves to be most suitable [5].…”

Main Problems of Nanostructured Materials Science

“…The phenomenon of "non-repeating" is characteristic of many new technologies. It is assumed that this question is not connected only with the strong regime maintenance, but also with increased dynamic instability of chaotic systems [26,27]. Nanostructures with their deviation from equilibrium state and great volume and surface fluctuations are believed to belong to chaotic systems.…”
