论文摘要
最近预计CU3SN可以容纳拓扑迪拉克费米,但相关研究仍处于起步阶段。因此,高质量和高质量的CU3SN单晶的生长非常希望研究可能的拓扑特性。在这项工作中,我们报告了Czochralski(CZ)方法的CU3SN的单晶生长。分析了Cu3SN单晶的晶体结构,化学成分和转运性能,以验证晶体质量。值得注意的是,与来自熔融SN液的MM尺寸晶体相比,通过CZ方法获得的CM大小晶体免受通量材料的污染,为后续工作铺平了道路。
Cu3Sn was recently predicted to host topological Dirac fermions, but related research is still in its infancy. The growth of large and high-quality Cu3Sn single crystals is, therefore, highly desired to investigate the possible topological properties. In this work, we report the single crystal growth of Cu3Sn by Czochralski (CZ) method. Crystal structure, chemical composition, and transport properties of Cu3Sn single crystals were analyzed to verify the crystal quality. Notably, compared to the mm-sized crystals from a molten Sn-flux, the cm-sized crystals obtained by the CZ method are free from contamination from flux materials, paving the way for the follow-up works.
