CRYSTAL-GROWTH OF ANTIMONY SULFUR IODIDE

Single crystals of SbSI have been grown from SbI3 flux by directional cooling through a temperature gradient. The morphology of the crystals is found to be dependent on the growth parameters: (1) composition of the mixture of Sb2S3 and SbI3 flux; (ii) temperature gradient, and (iii) rate of lowering (or cooling). Single crystals highly oriented parallel to the ferroelectric c-axis can be produced by this method in the form of fine parallel needles, thin parallel plates and larger size plates. Characterization information and a brief description of some applications for the single and polycrystal forms produced are given. © 1979.
