Effect of passivation on stress relaxation in electroplated copper films

WebThe relaxivity (relaxation rate per mM ferritin) increases quickly with initial iron loading, reaches a peak at 13-14 Fe atoms per mol., and then declines. This provides supportive evidence for the formation of antiferromagnetically-coupled clusters during early stages in iron loading; the failure to see a similar peak in an earlier study may be related to the … Web29 Dec 2010 · Quantifying the Stress Relaxation Modulus of Polymer Thin Films via Thermal Wrinkling ... of the trilayer film was placed onto t he heated hot-stage for an annealing time of at least 3600 s.
