DISSOLUTION RATE OF GaP CRYSTAL ON A CENTRIFUGE

摘要

The dissolution rate of a GaP(111)B facet into gallium was measured in real time at accelerations from 1.1 to 7.0 g using NIR microscopic interferometry. The dissolution rate was remarkably decreased at a particular value of the rotation rate where the Coriolis-Buoyancy balance model predicts. This result indicates that the model can describe fluid behavior with the condition that the centrifuge has a small radius. Two non-dimensional parameters were derived from the model that characterize the behavior of low-Pr fluids such as liquid metals and semiconductors.
