The composition conversion mechanism of InSb into InGaSb when an In–Ga–Sb solution was in contact with an InSb substrate was investigated. Striations were formed in the conversion region by passing electric current pulses. This indicated that the solid and the liquid coexisted during the conversion process. After removing the solution from the substrate, the Ga profiles became smoother and deeper with the increase of annealing period and with the decrease of cooling rate. This proved that the Ga could move down into the InSb substrate during these processes. By the direct observation of the movement of the conversion region on an InSb substrate using a high-temperature optical microscope, the appearance of the {111} facet at the moving front of the region was confirmed. The gradual dissolution of InSb led to the formation of In–Ga–Sb solution belt in the substrate and the subsequent crystallization of InGaSb.
