Diffusion-controlled deformation mechanisms may become relevant for nanocrystalline and nanostructured materials at room temperature. In this paper, the stress–strain behavior of gold nanowires 40nm wide, 20nm high and 1mm long on a flexible substrate was investigated in the temperature range of 173–393K. For decreasing temperatures, the yield strength and the fracture resistance increase. Both can...
Metallic conductors on polymeric substrates are frequently used for printed circuit boards or flexible displays. Optimization of these devices is mostly associated with the miniaturization of the conductors which changes their electrical and mechanical properties. We focus on crack formation in gold nano-interconnects about 20nm high, 40nm wide and 1mm long on flexible substrates. The fracture toughness...
