标题： Phosphorene Junctions as a Platform for Spin-Selective Quantum Dots in Next-Generation Devices

摘要： 研究了磷烯基结中空位对量子点（QDs）自旋分辨电子性质的影响，采用数值方法进行了探讨。 无论晶体取向如何，含有单空位的磷烯纳米带（PNR）被发现表现出一种出现在带隙内的拓扑准平带。 量子点的电子性质，包括空间限制和能级分布，可以通过控制量子点的拓扑结构以及施加电场来强烈调节。 此外，在铁磁交换场下，这些量子点表现出显著的自旋选择性特性，从而实现对量子点特性的操控。 这为量子计算、磁传感和基于自旋的发光等新应用开辟了可能性。 显示英文摘要

摘要： The impact of vacancies on spin-resolved electronic properties of quantum dots (QDs) in phosphorene-based junctions, are investigated numerically. Regardless of the crystal orientation, a phosphorene nanoribbon (PNR) containing a monovacancy is found to exhibit a topological quasi-flat band that emerges within the band gap. The electronic properties of QDs, including spatial confinement and energy level distribution, can be strongly tuned by controlling the topological structure of the QDs and by applying electric fields. Additionally, these QDs exhibit remarkable spin-selective properties under a ferromagnetic exchange field, enabling the manipulation of QD features. This opens up the potential for novel applications such as quantum computing, magnetic sensing, spin-based light emission.
