Defect and Diffusion Forum, 439 291-304, Feb 20, 2025 Peer-reviewedIn this study, we proposed a moved-view analysis, a method for obtaining the Soret coefficient ST by analyzing the interference fringe change during field-of-view movement in the steady state. This analysis was designed to solve the problem that the sign of the concentration gradient could also be reversed if the plot of the concentration distribution was only slightly shifted owing to the narrow field of view. The data obtained from the experiment conducted to measure ST at the International Space Station were analyzed using moved-view analysis. For the moved-view analysis, the linearity of the concentration distribution induced by the Soret effect is larger than that for the method without field-of-view movement, and a more reliable ST can be obtained. The analysis error that sometimes occurred when the laser wavelength switched led to the underestimation of the phase change Δϕ, resulting in generating the data with low linearity. This unreliable data should be removed.

NCTAM papers, National Congress of Theoretical and Applied Mechanics, Japan, 64 OS7-5, 2017<p>InGaSb crystals have been grown on the International Space Station using a GaSb (feed) / InSb / GaSb (seed) sandwich-structured sample. To shed light on the experimental results, numerical simulations were carried out to investigate the transport phenomena and mechanisms during the dissolution process of InGaSb crystal under zero-gravity. Simulation results showed that the dissolution lengths of feed and seed crystals were determined by the temperature along the seed interface. The results also indicate a 3 K temperature difference between the inside growth ampoule and the outside cartridge.</p>
