使用配备力传感器来测量弹簧常数的透射电子显微镜 (TEM) 支架对沿 [110] 方向拉伸的金 (Au) 纳米触点 (NC) 进行分析。无论在接触的两根金丝拉伸过程中形成的 NC 的初始形状如何，Au NC 的弹簧常数随电导的变化都表现出类似的变化。 Au NC 的杨氏模量估计接近体积值。这项研究展示了 TEM 组合方法通过了解纳米材料的形状和尺寸来表征其机械性能的性能。 (C)2020 日本应用物理学会
Gold (Au) nanocontacts (NCs) being stretched in the [110] direction were analyzed using a transmission electron microscopy (TEM) holder equipped with a force sensor to measure spring constants. The Au NCs showed similar change in spring constant with electrical conductance, regardless of the initial shape of NC formed during stretching of contacted two Au wires. The Young's modulus of the Au NC was estimated to be close to the bulk value. This study demonstrated the performance of TEM-combined method to characterize the mechanical properties of nanomaterials via knowing their shape and size.
