项目摘要
The project aims at the investigation of structural, magnetic and electric properties of MnAs/GaAs and MnAs/InAs hybrid nanowire structures with well-defined cluster properties. The hybrid structures are fabricated by selective-area metal organic vapor phase epitaxy (SA-MOVPE) of InAs or GaAs nanowires. In a second growth step the ferromagnetic MnAs nanoclusters are formed during an endotaxy process on the facets of the nanowires, whereas the cluster properties can be tuned systematically by varying the growth conditions. The influence of the nanoclusters as well as of co-doping on the electrical properties of the hybrid nanowires is investigated using magnetotransport and Seebeck measurements and the results are correlated with the structural and magnetic properties of the MnAs nanoclusters. Major goal of the project is to obtain a fundamental understanding of the influence of the nanoclusters on the underlying mesoscopic transport processes and to evaluate the potential of such hybrids for future application in the field of nano-magnetoelectronics and nano-spintronics.
该项目旨在研究具有明确簇特性的MnAs/GaAs和MnAs/InAs混合纳米线结构的结构,磁性和电学性质。该混合结构是通过选择区域金属有机气相外延(SA-MOVPE)的InAs或GaAs纳米线。在第二生长步骤中的铁磁性的MnAs纳米团簇的形成过程中的纳米线的刻面上的endotaxy过程中,而集群的性能可以通过改变生长条件系统地调谐。的纳米团簇以及共掺杂的混合纳米线的电性能的影响进行了研究,使用磁输运和Seebeck测量和结果与结构和磁性的MnAs纳米团簇。该项目的主要目标是获得一个基本的理解的影响的纳米团簇的基本介观输运过程,并评估这种混合动力车在纳米磁电子学和纳米自旋电子学领域的未来应用的潜力。
