论文摘要
我们提出了一种新的方法，用于生成横向谷电流，该方法基于由纯$α-\ Mathcal {t} _3 _3 $ lattices与铁磁性诱导的交易所交流相互作用组成的超导杂交连接中的纯交叉Andreev反射（PCAR）。对于给定的山谷而言，角度分辨的PCAR概率是不对称的，导致横向山谷电流为零净电荷。这种PCAR辅助电荷 - Valley的转换非常有效，山谷大厅的角度达到了统一的顺序，这表明了Valleytronic设备的潜在应用。
We propose a novel method for the generation of the transverse valley currents, which is based on the pure crossed Andreev reflection (pCAR) in the superconducting hybrid junctions composed of the gapped $α-\mathcal{T}_3$ lattices with ferromagnet-induced exchange interaction. The angle-resolved pCAR probability is asymmetric for a given valley, resulting in the transverse valley currents with zero net charge. This pCAR assisted charge-valley conversion is highly efficient with the valley Hall angle reaching an order of unity, suggesting potential applications for valleytronic devices.
