摘要:

从实验和理论两方面研究了用机械可控断裂结或扫描隧道显微镜形成的Ni纳米线在拉伸时的动态变形。对破碎过程进行了分子动力学模拟。此外,为了与实验进行比较,我们还计算的传输属性在失败之前的最后阶段使用的第一性原理实施的Landauer的形式主义包括在我们的运输包ALACANT。

英文摘要:

The dynamic deformation upon stretching of Ni nanowires as those formed with mechanically controllable break junctions or with a scanning tunneling microscope is studied both experimentally and theoretically. Molecular dynamics simulations of the breaking process are performed. In addition, and in order to compare with experiments, we also compute the transport properties in the last stages before failure using the first-principles implementation of Landauer's formalism included in our transport package ALACANT.
