We have reported the formation of InSb particles using a short-drop tube process. Most InSb particles produced by in this manner indicated polycrystalline structure, and the condition for the formation of single crystalline particles has not been clear. In this study, we focused on the difference in the melt temperature condition and solidification process of each particle, and aimed to examine the factor controlling formation of single crystalline InSb particles. We have investigated the relationship between melt temperature, solidification time, and surface structure of InSb particles and aimed to improve the frequency of formation of single crystalline particles. Consequently, we concluded that slow crystal growth from low temperature is effective for the formation of single crystalline particles of InSb. The rate of smooth surface particles that indicated single crystalline structure was improved in InSb particles produced in He atmosphere at a pressure of 0.5 atm from above the melting point of the InSb compound phase compared with those formed by the conventional method.
