我们研究了在分子束外延生长的自催化GaAs纳米线中掺入锰。我们的研究表明,锰积聚在液态Ga液滴中,并且没有观察到明显掺入纳米线中。使用顺序结晶的液滴,然后,我们证明了一个确定性和外延生长的MnAs段在纳米线尖端。这种技术可以允许多个室温铁磁段无缝集成到GaAs纳米线与高结晶质量。
We investigate the incorporation of manganese into self-catalyzed GaAs nanowires grown in molecular beam epitaxy. Our study reveals that Mn accumulates in the liquid Ga droplet and that no significant incorporation into the nanowire is observed. Using a sequential crystallization of the droplet, we then demonstrate a deterministic and epitaxial growth of MnAs segments at the nanowire tip. This technique may allow the seamless integration of multiple room-temperature ferromagnetic segments into GaAs nanowires with high-crystalline quality.
