摘要:

纯自旋电流的自旋电子器件代表了纳米电子学的新范式,与电荷电流相比,具有更高的能量效率和更低的耗散。然而,这种技术只有在纳米通道中扩散的自旋电流量可以根据需要进行调整,同时保证与其他器件元件的电兼容性时才是可行的,它应该集成在高密度三维架构中。在这里,我们解决这两个关键的里程碑,并证明纯自旋电流可以有效地传播在金属纳米通道与三维弯曲的几何形状。值得注意的是,纳米通道的几何设计可用于实现自旋输运和电荷输运特性的独立调节。这些结果为设计高效的纯自旋电流电子器件奠定了基础,这些电子器件可以集成在复杂的三维结构中。

英文摘要:

Spintronic devices operating with pure spin currents represent a new paradigm in nanoelectronics, with higher energy efficiency and lower dissipation as compared to charge currents. This technology, however, will be viable only if the amount of spin current diffusing in a nanochannel can be tuned on demand while guaranteeing electrical compatibility with other device elements, to which it should be integrated in high-density three-dimensional architectures. Here, we address these two crucial milestones and demonstrate that pure spin currents can effectively propagate in metallic nanochannels with a three-dimensional curved geometry. Remarkably, the geometric design of the nanochannels can be used to reach an independent tuning of spin transport and charge transport characteristics. These results put the foundation for the design of efficient pure spin current based electronics, which can be integrated in complex three-dimensional architectures.
