In polycrystalline materials where transgranular cleavage is the preferred fracture mode, the crystallographic misorientation of fracture planes across grain boundaries can provide resistance to crack …
For non-stoichiometric oxide thin films (e.g. ceria and titania) in constrained geometries the variation in oxygen partial pressures lead to stresses, thus termed compositional stresses. …
In order to understand the stress behaviors in thin films, three related topics were investigated. First, intrinsic stress generation mechanisms were studied by in-situ stress …
