Main achievements

  • New models have been developed that describe the mechanical properties of crystals, nano/microtubes made of them and layered composites using the theory of elasticity of an anisotropic body. The features of the mechanical behavior of materials with negative Poisson's ratio (auxetics) have been revealed. Models and designs of medical stents with auxetic properties have been developed (in cooperation with the laboratory of laser discharges).

  • In application to the technology for the production of very-large-scale integration circuit (VLSI) using the dislocation-free silicon single crystals of large diameters (200–300 mm), the mechanical-mathematical models, algorithms and a program code have been developed to describe heat and mass transfer processes in the melt and the grown crystal, the formation of growth defects, and also to optimize the designs of hot zones of growth equipment and the conditions for growing single crystals, providing the required content reduction and sizes of technological defects. The technological innovations have provided Czochralski process optimization of growing silicon single crystals from a melt by means of the special designs of the heat shield for the domestic heavy-charge furnace "Redmet-90M".

Experimental equipment

  • The setup "TH-2" ("Technological Hydromechanics-2") for physical modeling of thermo-mechanical processes in application to Czochralski crystal growth has been produced in 1992–1996 by the manufacturing of IPMech RAS. This setup has high-precision, low-inertia rotation and linear displacement drives, high axial symmetry of the crystal and crucible simulators, and a reliable temperature control system for working surfaces. In the course of its application in the following years, the TH-2 setup was permanently modernized and equipped with the modern measuring and data processing facilities during IPMech RAS programs and RFBR grants.

  • The setup "TH-3" ("Technological Hydromechanics-3") for studying the features of thermo-mechanical processes during Czochralski crystal growth has been produced in 2017–2019 in the framework of the RFBR grant 17-08-00078-a. The modeling materials with a low melting point (up to 380°C) were grown under ordinary atmospheric conditions on this "TH-3" setup. For these researches a sodium nitrate was used, the melt of which is transparent. This has been provided the possibilities of temperature measurements and also visualitions of convective flows in a melt.
