RESULTS
Eight single crystals of indium antimonide (InSb), doped with tellurium and zinc, were
directionally solidified in microgravity. The molten semiconductor material solidified as
expected, without separating from the ampoule walls or releasing the undesirable bubbles that
have been reported in several previous microgravity investigations. Semiconductor crystals with
reproducible, nearly identical composition were obtained for the first time in space.
