摘要
The fracture strain, strength, and flexibility of ZnO nanowires (NWs) with a large range of diameters (85-542 nm) are investigated at a quantitative level. Large strains up to 4%-7% have been obtained before the final elastic fracture, corresponding to fracture strengths close to the theoretical strength. The flexibility of a NW is discussed quantitatively in terms of the diameter and fracture strain. The fundamental mechanisms responsible for the observed exceptional properties are discussed.
