In this paper, spin split, spin-polarization, and spin-flip effect were theoretically investigated through a three-terminal phosphorene quantum nanoring (PQNR) by using the Green’s function formalism in the presence of Rashba spin–orbit interaction (RSOI) and penetrating magnetic flux inside the ring. Our results show that the perfect spin splitting occurs because of the PQNR anisotropic structure. Furthermore, the spin polarization can be tunned by the RSOI strength and the energy of incident electrons. Consequently, this configuration can provide an efficient way to control the spin-dependent transport. Moreover, the structure can illustrate the full spin-flip effect that is irrespective of the injection source.

在本文中，在格林尼治碱存在的Rashba自旋-轨道相互作用（RSOI）和穿透作用下，通过格林函数形式论，通过三端phosphor量子纳米环（PQNR）对自旋分裂，自旋极化和自旋翻转效应进行了理论研究。环内部的磁通量。我们的结果表明，由于PQNR各向异性结构，发生了完美的自旋分裂。此外，可以通过RSOI强度和入射电子的能量来调整自旋极化。因此，该配置可以提供控制自旋相关传输的有效方式。此外，该结构可以说明与注入源无关的完全自旋翻转效果。
