| Research Abstract |
A permanently bending technique of nanowires (NWs) was developed using misfit strain due to dissimilar material coating. The driving force of the bending is the residual stress. The novel mechanical process relies on a bending enhancement, where an NW's constraint against the bending deformation is removed by elevating temperature for inducing creep flow only in the NW. Theoretical investigations were also made in terms of molecular dynamics simulations and continuum mechanics. Furthermore, a manipulator was built for gripping and positioning an NW. With a help of the manipulator, the bending technique demonstrated the fabrication of micro/nanocoils.
