Un bicristal mince déformé sous l'effet d'un réseau bipériodique de dislocations de misfit

Abstract

The elastic field of a planar two-period network of misfit dislocations parallel to the two free surfaces of a thin bimaterial is explicitly determined from the assumption of an isotropic elasticity for each crystal. A few calculations of normal stresses enable the elastic field relaxation to be illustrated for CoSi₂/Si(111).
