摘要：
Single crystals of AgGaS2 were grown by the Bridgman-Stockbarger technique using fused square cross-section ampoules with a carbon coating. Melt growth was performed by self-seeding as well as with seeds oriented with their [001] direction parallel to the ampoule axis. Both procedures yielded high quality single crystals up to 40 mm in length. Optically clear crystals could be obtained by using feed material received from earlier solidification experiments. Compositional variations in growth direction could not be determined.
