Internal size effect of melting in the layered film system of eutectic type


Adhesion of Melts and Brazing of Materials - Kiev: Frantsevich Institute for Problems of Materials Science NASU, 2008, #41


This article presents results of the investigation of the melting processes in thick (~400 nm) Bi-Sn eutectic bi- and multi-layer systems. Measurements of multilayer system (layer thickness 10-20 nm) and bilayer system (layers thickness ~200 nm) of similar total sickness have demonstrated that eutectic melting temperature for a multiplayer system is lower than for a bilayer system. Thermodynamic analysis has shown that temperature reduction depends on total thickness of the neighboring layers and layers boundary energy.
