Growth and mechanical properties of metal nanowhiskers

Abstract eng:
Single-crystalline, defect and flaw free nanowhiskers were grown by physical vapour deposition under ultra-high vacuum conditions. The investigated microstructure of the nanowhiskers is unique, no dislocations or grain boundaries were detected. The shape of the prismatic body can be explained by a classical Wulff theorem. The mechanical properties of the nanowhiskers were investigated by tensile and bending set-ups. For both set of experiments mechanical strength close to the predicted theoretical values were found. The onset of plasticity is determined by the nucleation and propagation of Shockley partial dislocations. Advanced nanostructures based on said nanowhiskers are also reported and their behaviour under mechanical loading is presented.
