nanopriodic dislocation network at the GaSb/GaP interface. Nevertheless, the coherent length of thisnetwork is small and a high <strong>de</strong>nsity of threading <strong>de</strong>fects remains.That is the reason why we would like to associate this particular relaxation mo<strong>de</strong> to the selectivegrowth of nanometric seeds (nanoepitaxy), with dimensions smaller than the coherent length of thedislocation network. These seeds will then allow, upon coalescence, the growth of high structuralquality ribbons and 2D layers for the fabrication of electronic nano<strong>de</strong>vices.49
