Abstract

A high quality GaSb bicrystal was grown in a Bridgman type arrangement under microgravity conditions on board of Salyut-6. Rutherford back-scattering measurements indicate oxide and damage free surfaces. Scanning Electron Microscopy revealed microfacets on the space grown sample. The morphology of the sample suggests a crystallization quite free of a wall effect. A comparison is given between space and terrestrial GaSb ingots, showing differences in surface quality, crystal perfection and hole mobilities. In the space grown sample a μmh ≈ 2700 cm2 v-1 s-1 value was found while for the terrestrial control this value was only 2000 cm2 v-1 s-1.
