Growth optimization of thin filmsWithin the project, for the realization of thin multilayer films, we plan to use three deposition techniques, all compatible with current device architectures. The key point here is to ensure the best structural material quality, in order to reduce the spurious effect on the physical properties given by, for instance, imperfections, such as grain boundaries. This approach enables the production of the best structures and it will be advantageous for revealing self-adjusting mechanisms as those depending on spinodal decomposition or intermixing at interfaces. The fabrication effort of many heterostructures development of four groups will be summarized. This deliverable relates to WP2 and specifically to task 2.1.

Atomic structure characterization and modelling of optimized thin filmsStructural and compositional characterization down to the atomic level will be reported.

In addition the interplay of spectroscopic techniques like EELS and EDX with STEM imaging will be discussed. It will be reported on ab-initio MD simulations to study (1) the relative stabilities of amorphous and crystalline phases at the interfaces and (2) the phase change mechanism within the heterostructures.
