Cleavage cracking across twin boundaries in free-standing silicon thin films

چکیده

Cleavage cracking across twin boundaries in freestanding silicon thin films is investigated in a microtensile fracture experiment. If the twist misorientation is relatively small, the crack front transmission can be quite smooth; otherwise the fracture surface may be either planar or broken down into parallel terrains. In all the cases, the local fracture resistance tends to increase. PACS 62.20.-x; 68.35.bg; 68.35.Gy; 68.37.-d; 62.20.mm

Resistance of through-thickness grain boundaries to cleavage cracking in silicon thin films

Through a set of microtensile experiments, it was discovered that the resistance of a free-standing polycrystalline silicon thin film to cleavage cracking is not a material constant. Rather, it is highly dependent on the film thickness. As the film thickness changes from 1 to 10 lm, the fracture resistance increases by 20–60%, which can be attributed to the nonuniform nature of the crack front ...

Secondary cracking at grain boundaries in silicon thin films

In this article, we report irregular cleavage front transmission at grain boundaries in free-standing polysilicon thin films. When the orientations of two adjacent grains are correlated, the crack may bypass the boundary via a ‘‘tunneling’’ process. Similar behavior can also be achieved if the crack path curves in the grain-boundary-affected zone. Moreover, the separation of crack flanks can be...

On size effect of cleavage cracking in polycrystalline thin films

A crack trapping model is developed for the fracture resistance of high-angle grain boundaries in free-standing brittle thin films, based on which a new size effect is predicted. In addition to the crystallographic misorientations, the grain boundary toughness is also dependent on the film thickness, primarily due to the geometrically necessary crack front branching. 2007 Elsevier Ltd. All righ...

Interaction of cleavage ridges with grain boundaries in polysilicon films

The morphology of cleavage surfaces across grain boundaries in free-standing silicon thin films was investigated. Three ridge–boundary interaction modes were identified. If the cleavage ridge was relatively deep, it could directly bypass a grain boundary. If it was relatively shallow, it would act as a stress concentrator promoting cleavage front transmission. It was also observed that due to t...

Resistance of grain boundary array to cleavage cracking in free-standing thin film

In a previous experimental study on free-standing silicon thin film, it was observed that cleavage front transmission across a through-thickness grain boundary could be considerably constrained by film surfaces. As a result, the boundary toughness was much lower than its bulk counterpart. In this study, inspired by the observation of crack front behaviors at triple grain boundary junctions, we ...
