The comparative analysis of the results of space and ground-based experiments IMET RAS on the growth of InSb:Te crystals by the Bridgman method and floating zone method (FZM) is made for the purpose of studying the influence of microgravity on the growth, structure, and properties of grown crystals, and thus the gravity sensitivity of InSb melt is demonstrated. It is shown that, under microgravity conditions, the Bridgman method makes it possible to grow InSb:Te crystals without contact with the ampoule walls, which provides for the single crystal structure, the absence of striations, and a low dislocation density. For the first time, InSb:Te monocrystals were grown with the FZM under microgravity. The anomalous behavior of the impurity core (facet effect) in these crystals correlates with the changed magnitude and direction of the quasi-stationary (residual) microaccelerations.
