Buckle delamination on patterned substrates
Lithographic techniques applied to a substrate prior to film deposition can create areas of low interface adhesion surrounded by regions of high adhesion. If the film is under compression and if buckle delamination is nucleated, conditions can be controlled such that delaminations are confined to the patterned areas of low adhesion. When the area of low adhesion is a strip, the width of the str...
متن کاملDelamination of stiff islands patterned
In one design of flexible electronics, thin-film islands of a stiff material are fabricated on a polymeric substrate, and functional materials are grown on these islands. When the substrate is stretched, the deformation is mainly accommodated by the substrate, and the islands and functional materials experience relatively small strains. Experiments have shown that, however, for a given amount o...
متن کاملPatterned Nanomagnetic Films
Nano-fabrication technologies for patterned structures made from thin films are reviewed. A classification is made to divide the patterning technologies in two groups namely with and without the using a mask. The more traditional methods as well as a few new methods are discussed al in relation with the application. As mask less methods we discussed direct patterning with ions including FIB, na...
متن کاملNonlinear Delamination Mechanics for Thin Films
Delamination of prestressed thin films on thick substrates is analysed accounting for plastic dissipation in either the substrate or film. Emphasis is on large scale yielding wherein the height of the plastic zone at the propagating interface crack tip is comparable to the film thickness. Such conditions are common for both metal and polymer thin films on elastic substrates or for ceramic coati...
متن کاملPatterned nanostructure in AgCoÕPtÕMgO„001... thin films
The formation of a patterned nanostructure in an AgCo/Pt/MgO~001! thin film is simulated by a technique of combining molecular dynamics and phase-field theory. The dislocation ~strain! network existing in Pt/MgO is used as a template whose pattern is transferred to the AgCo phase in spinodal decomposition, resulting in regular arrays of Co islands that are attracted by the dislocations. The inf...
