In this study, we have investigated the single crystalline particle formation of InSb and GaSb 111-V type semiconductors by using the drop tube apparatus with a free fall length of 2.5 m. Microstructure and crystal orientation of the fine particle samples prepared by the drop tube process were measured by using SEM-EBSD. The samples were classified into two surface patterns: one is rough, the other is smooth. The sample with rough surface showed a polycrystalline structure, while the sample with smooth surface showed a single crystal formation.
