摘要：

Deformation properties of multi-wall gold nanowires under compressive loading are studied. Nanowires are simulated using a realistic many-body potential. Simulations start from cylindrical face-centred cubic (111) structures at T = 0 K. After annealing cycles, axial compression is applied to multi-shell nanowires for a number of radii and lengths at T = 300 K. Several types of deformation are found, such as large buckling distortions and progressive crushing. Compressed nanowires are found to recover their initial lengths and radii even after severe structural deformations. However, in contrast to the case for carbon nanotubes, irreversible local atomic rearrangements occur even under small compressions.
