论文摘要
许多现代的自旋技术技术，例如自旋阀，旋转大厅的应用和自旋THZ发射器，都是基于金属纳米结构中埋藏的内部接口的电子。但是，这种纳米结构内的复杂电流途径很难使用常规的实验方法解散。在这里，我们使用THZ时域光谱法以无接触式的方式来测量技术相关的RU/CO BiLayer纳米结构的电导率。通过将有效的电阻网络应用于数据，我们可以解决纳米结构内的复杂电流途径，并确定RU和CO纳米层之间内部界面的电子透明度。
Many modern spintronic technologies, such as spin valves, spin Hall applications, and spintronic THz emitters, are based on electrons crossing buried internal interfaces within metallic nanostructures. However, the complex current pathways within such nanostructures are difficult to disentangle using conventional experimental methods. Here, we measure the conductivity of a technologically relevant Ru/Co bilayer nanostructure in a contact-free fashion using THz time-domain spectroscopy. By applying an effective resistor network to the data, we resolve the complex current pathways within the nanostructure and determine the degree of electronic transparency of the internal interface between the Ru and Co nanolayers.
