Abstract
A study of submicron single crystal Au pillar, before and after uniaxial plastic deformation, is discussed in this chapter. There is no evidence of measurable lattice rotation or lattice bending/polygonization due to the deformation up to a plastic strain of about 35 % and a flow stress of close to 300 MPa. These observations, coupled with other examinations using electron microscopy, suggest that plasticity here is not controlled by strain gradients, but rather by dislocation source starvation.
