Abstract
Phase-Coherent Transport
In article number 2300565, Prateek Kaul, Dan Buca, and co-workers perform magneto-transport measurements on Hall bar devices on the novel alloy system GeSn grown on a Si wafer. The measurements reveal robust phase-coherent transport in high Sn concentrations with weak-localization effects and Shubnikov-de Haas oscillations (pictured). These are further used to extract coherence length, mobility and effective mass of Gamma-valley electrons in direct bandgap GeSn, setting forward a baseline for further experiments on the novel material system for its electronics, spintronics, and quantum computing applications.
文章编号2300565，Prateek Kaul， Dan Buca及其同事在硅晶片上生长的新型合金体系GeSn上对霍尔棒器件进行了磁输运测量。测量结果显示，在高锡浓度下，强相参输运具有弱局域效应和舒布尼科夫-德哈斯振荡（如图）。这些进一步用于提取直接带隙GeSn中γ -谷电子的相干长度、迁移率和有效质量，为进一步在新型材料系统上进行电子学、自旋电子学和量子计算应用的实验奠定了基础。
