用提拉法生长了高质量、大尺寸、具有混合钙钛矿结构的 (La ,Sr) (Al,Ta)O3 晶体 (LSAT) ,晶体尺寸达5 5mm×5 0mm。讨论了晶体生长有关工艺 ,并对晶体的完整性进行了初步研究。
High-quality, large-size (La, Sr) (Al, Ta) O3 crystals (LSATs) with mixed perovskite structures were grown by Czochralski method with a crystal size of 5mm5 5mm × 50mm. The technology of crystal growth is discussed, and the crystal integrity is studied preliminarily.
