WebJan 23, 2013 · A whisker and hillock growth model based on local film microstructure, grain misorientation, and elastic strain energy density (ESED) as the driving force for growth was developed to predict preferred sites for growth. WebAug 1, 2000 · The formation of hillocks was examined in various Pt/Ti electrodes with similar thermal histories, which were annealed prior to PZT film deposition by the sputtering method.
WebThe significance and mechanism of their formation are unknown. To determine whether a proliferative component is involved in hillock formation, cells were treated with heparin or irradiated to inhibit proliferation. Heparin caused a 50% inhibition of mesangial cell growth and stimulated hillock formation three-fold to fourfold. WebJun 19, 2024 · This results in the formation of nano-structures such as hil-lock-like protrusions on the surface [8–11] or the formation of craters [12, 13]. Comparable hillock-like structures were also found on various surfaces irradiated with HCIs and SHIs [3]. Unlike the prior mentioned process leading to the formation of nano-

WebOct 23, 2024 · Stress relaxation in thin metal films often results in formation of hillocks—high grains protruding from the rest of the film. Their formation is discussed in terms of surface diffusion and accumulation of the film material, as well as in terms of material accretion at the film–substrate interface and grain boundary sliding. We …
