论文摘要
我们研究了由一维系统和二维系统中线性和立方自旋轨道相互作用引起的非线性转运特征。有限的温度数值分析可以补充对外部场的分析零温度响应，从而建立了一种区分线性和立方旋转轨道相互作用的方法。我们还提出了一项协议，以确定可在现实条件下可实现的运输测量值的相关材料参数，这是由GE异质结构的值所说明的。我们的结果为半导体纳米结构中自旋轨道特性快速基准测试建立了一种方法。
We investigate non-linear transport signatures stemming from linear and cubic spin-orbit interactions in one- and two-dimensional systems. The analytical zero-temperature response to external fields is complemented by finite temperature numerical analysis, establishing a way to distinguish between linear and cubic spin-orbit interactions. We also propose a protocol to determine the relevant material parameters from transport measurements attainable in realistic conditions, illustrated by values for Ge heterostructures. Our results establish a method for the fast benchmarking of spin-orbit properties in semiconductor nanostructures.
