Origin of the first-phase selection during thin film reactive diffusion: Experimental and theoretical insights into the Pd-Ge system

Résumé

Pd-Ge reactive-diffusion in two different samples Pd/Ge(001) and Pd/PdGe/Ge(001) was studied experimentally and theoretically, in order to clearly identify the driving force controlling the first-phase selection in the sequential phase formation regime. The experimental and theoretical results both show that only the atomic transport kinetic in the phases controls the first -phase selection: the phase exhibiting the fastest atomic self-diffusion forms first, even if its formation energy is not the lowest.
