Numerical 2D modelling of turbulent melt flow in CZ system with dynamic magnetic fields

Prediction of the growth interface shape in industrial 300mm CZ Si crystal growth

“…The heat transfer in the region below the crystal seems to be mainly influenced by turbulent mixing rather than convection due to the mean flow. That finding is in line with results of recent CZ model experiments performed at the Institute of Physics, Riga, Latvia [6]. Fig.…”

“…Recent experimental results from a CZ model facility described in Ref. [5,6] do also confirm strong temperature fluctuations in the subcrystal region. Fig.…”

Numerical 3D modelling of turbulent melt flow in large CZ system with horizontal DC magnetic field—I: flow structure analysis

“…The comparison with measurements, described in detail in Ref. [8], shows that the calculations describe correctly the main features of temperature distributions. There is good agreement between calculated and experimentally measured temperature distributions in the vertical cross-section of the melt, and weaker agreement between distributions in the horizontal cross-section.…”

Thermodynamics, Origin, and Control of Defects

“…at the congruent melting or vaporization point in case of melt or vapor growth, respectively, and ii) the choice of undercritical growth velocities. Furthermore, accelerated crucible rotation techniques [102,103], control by ultrasonic [104,105] or nonsteady magnetic fields [106] can be assumed as effective additional steps to disassemble phase boundary layers in future melt-growth processes.…”
