Experimental conductivity measurements made during highly stable tensile deformation of Au nanowires show a rich variety of behaviors, including noninteger quantum conductance plateaus, transitions, and slopes. Using tight binding conductance calculations on simulated nanowires previously deformed using density functional theory, we demonstrate that all of these phenomena arise from structural transitions between deeply metastable ordered atomic configurations that self-organize during tensile deformation.
在 Au 纳米线的高度稳定拉伸变形过程中进行的实验电导率测量显示出丰富的行为，包括非整数量子电导平台、跃迁和斜率。使用基于密度泛函理论模拟的纳米线进行紧束缚电导率计算，我们证明所有这些现象都源于在拉伸变形过程中自组织的深亚稳态有序原子构型之间的结构转变。
