Abstract
GaSb was synthetized from Ga of 6N and Sb of 5N5 purity. After the synthesis the crystallization took place in Bridgman-type growth systems. Terrestrial and space experiments aboard Salyut-6 have been performed. In terrestrial experiments depending on the growth parameters (pulling rate, ampoule diameter, etc.) macro−, or polycrystalline ingots showing a characteristic texture have been formed. It has been observed that in wider ampoules boules of better quality have grown, the diameter of individual crystals ranging from 1–3 cm. In the space experiment a high-quality bicrystal has been formed. Examining the texture of terrestrial samples, the orientation of crystallites, the number of low and wide angle grain boundaries have been determined using electron channelling (EC) patterns.
