It is shown that very large stresses may be present in the thin films that comprise integrated circuits and magnetic disks and that these stresses can cause deformation and fracture of the material. For a crystalline film on a non-deformable substrat

The effect of grain boundaries (GB) on the buckling of an Al thin film delaminated from its substrate is investigated by means of molecular dynamics simulations at finite temperature. It is evidenced that the GB localizes the plasticity and deeply mo

The shape transition of a one-layer thick strained island deposited on a semi-infinite substrate has been theoretically investigated from an energy variation calculation. It is found that depending on the misfit strain, the initially circular island

Atomistic simulations based on experimental observations provide the first evidence that the interface delamination of a thin film from its substrate may start from interface steps. Buckling of the film after interface gliding from both edges of its

Gold single crystals were deformed by uniaxial compression tests with the help of an experimental apparatus that allows one to characterize in situ, by UHV scanning tunneling microscopy, the evolution of surface structures under stress. It is demonst

The effect of stress on the formation energy of H-platelets was studied through a 3D model based on elastic interaction by modelling the platelets as dislocation loops. A difference of self-formation energy between {111} and {100} platelets was estim

A theoretical model for the simultaneous thin film buckling and interface delamination from its substrate has been derived from a Griffith’s criterion which includes plastic events localized at the film–substrate interface. The predictions of the

In this paper we present a new model describing the temporal evolution for multi-instabilities of plastic deformation of stressed monocrystal. This model generalizes that with a single delay presented in [12,13]. The plastic instability is due to the
