Plastic deformation in initially defect-free Au nanowires has to be initiated by the nucleation of dislocations at the free surfaces into a perfect crystal. This dislocation nucleation process occurs at stress levels close to the theoretical shear strength of the single crystal. The thermally-activation of dislocation nucleation and the formation of defect structures during plastic… Continue reading Deformation behavior and mechanisms in defect-scarce Au nanowires

The Vector Foundation supports our efforts to elucidate with atomistic simulations the possibilities of organising point defects in a regular pattern from a random distribution.
