Plasticity in certain semiconductor materials at the nanoscale is actually linked to phase transformation rather than dislocation nucleation, as previously thought. This is shown by the results of an international research team led by Professor Roman Nowak of the Nordic Hysitron Laboratory (NHL) at Helsinki University of Technology, just published in the Nature Nanotechnology journal in an article entitled `An electric current spike linked to nanoscale plasticity`.
