We investigate the electromechanical and magnetic response of normal-zigzag phosphorene nanoribbons (nZPNRs) to the Dresselhaus spin-orbit coupling (SOC) and Rashba SOC, electric fields, exchange fields, and uniaxial strains. It is found that, when the typical exchange fields, developed by combining a ferromagnetic (FM) state with one of the antiferromagnetic (AFM) states, are applied to the system, spin and charge band splitting occur, simultaneously. We show that a zigzag phosphorene nanoribbon, when exposed to an FM and/or an AFM exchange field, as well as a transverse electric field, behaves as a half-metal, meaning that one spin state electrons are allowed to move. Furthermore, we demonstrate that the phosphorene nanoribbon undergoes a topological phase transition under a transverse electric field. By tuning the above parameters, one can control the transport properties of the system. Our results may have important applications in designing of spintronic devices based on phosphorene.

我们调查正态之字形phosphor纳米带（nZPNRs）对Dresselhaus自旋轨道耦合（SOC）和Rashba SOC，电场，交换场和单轴应变的机电响应。发现，当通过将铁磁（FM）状态与反铁磁（AFM）状态之一组合而形成的典型交换场应用于系统时，自旋和电荷带分裂同时发生。我们显示，之字形磷光体纳米带在暴露于FM和/或AFM交换场以及横向电场时，表现为半金属，这意味着一个自旋态电子被允许移动。此外，我们证明了ene纳米带在横向电场下经历了拓扑相变。通过调整以上参数，一个可以控制系统的传输特性。我们的结果可能在基于磷的自旋电子器件设计中具有重要的应用。
