摘要

Atomic-scale calculation on the elastic modulus and theoretical tensile strength of Au nanowires shows that they increase almost logarithmically with wire thinning. According to ab initio simulations, we attribute the improvement of the mechanical properties to the enhanced attraction between atoms due to surface induced electron charge redistribution.
