A scanning tunneling microscope supplemented with a force sensor is used to study the mechanical properties of a novel metallic nanostructure: a freely suspended chain of single gold atoms. We find that the bond strength of the nanowire is about twice that of a bulk metallic bond. We perform ab initio calculations of the force at chain fracture and compare quantitatively with experimental measurements. The observed mechanical failure and nanoelastic processes involved during atomic wire fabrication are investigated using molecular dynamics simulations, and we find that the total effective stiffness of the nanostructure is strongly affected by the detailed local atomic arrangement at the chain bases.

- Thermo-mechanical behavior of low-dimensional systems: The local bond average approach (2009, background): “According to ab initio calculations and STM measurements [59], the mechanical strength of the Au–Au bond is about twice that of the bulk value and the metals that form chains exhibit pronounced many-atom interactions with strong bonding in the lower-coordinated systems.”
- An object-oriented scripting interface to a legacy electronic structure code (2002, background): “Recent simulations 11,12 and experiments 13,14 show that in the process of breaking a piece of gold, we can create wires consisting of a single row of gold atoms (see Figure 3).”
