The mechanical properties of small objects deviate strongly from the bulk behaviour, as soon as their size becomes comparable or smaller to the dislocation mean free path (typically a few microns). For instance, their elastic limit increase when their size is reduced. On a another hand, nanostructures are exposed to strong constraints, such as that imposed by epitaxial relations with a substrate. Altogether, there is a clear need (supported by industrial interests) for a better understanding of the fundamental phenomena that govern the mechanical properties of materials at the nanometre scale. The lab SIMaP is engaged in this research and tackles the topic by combining sample growth, laboratory characterisation methods, numerical models, an...
