  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.
