Relaxation plastique d'un film mince par émission de dislocations filantes vis

Inclined misfit dislocations in a film/substrate system

“…Following results obtained in Ref. 30 on the same film/substrate system, but for a higher h ‐value, these legs be of pure screw character and glide in the γ and δ planes. As a result, only two couples of screw dislocations fulfill the continuity condition: …”

“…This particular problem was solved in Ref. 30 for a system GeSi/(001)Si. On the other hand, if ξ 1 and ξ 2 are interfacial dislocations, Fig.…”

“…For a semi‐infinite medium and a dislocation parallel to the free surface, a similar solution was also applied 28. Other solutions were presented but, to date, have not yet been applied to TEM simulations: one for the emerging dislocation problem 29 and the other for a dislocation line ‘refracting’ at the interface of a bicrystal 30, i.e. with an apex at the interface and a leg in each crystal.…”

“…18, established in isotropic elasticity, the model presented in Ref. 30 should be improved to include a non‐refracted angular dislocation with an apex kept at a distance from the interface.…”
