    Abstract

    A significant size effect on the mechanical properties of GaAs nanowires (NWs) is reported. A remarkable elastic strain of ≈11% for NWs with diameters of 50-150 nm and obvious plastic deformation in NWs with diameters ≤25 nm are revealed. The Youngs modulus of the NWs can be more than double that of bulk GaAs.
