Microravity experiments on melting and crystallization of InGaSb
2002
Abstract Drop experiments have been performed to study the crystallization of In 0.05 Ga 0.95 Sb and the melting behaviors of InSb and GaSb under different gravity conditions. Formation of spherical projections on the surface of InGaSb during its crystallization was in-situ observed using a high speed CCD camera. Spherical projections showed dependence of gravity during its growth. Indium compositions in the spherical projections were found to vary depending on the temperature. Melting velocities of InSb and GaSb crystals under the microgravity condition were found to be faster than those under normal gravity condition (1G).
