Phase formation and related morphological changes in two- and three-layer Ag-Ge films were
investigated in this work. It is shown that due to metal-induced crystallization initially amorphous
germanium layers can be converted into the crystalline state at 250 °C. Size effects of phase
formation in a binary system were investigated. Differences between bi- and tri-layer films are
observed in the context of their morphological evolution, which is consistent with the results of
studies of other binary structures. The observed features of the behavior of binary films are
explained within the framework of thermodynamic considerations.
The main scientific results have been obtained for the first time. Their scientific value is due
to the need to understand the relationship between the processes of phase formation and self-
organization. Practical value is related to the demand for germanium crystal layers of nanometer
thickness and the need to develop methods for creating modifying nanosized arrays. The next stage
of the project will be based on the use of such arrays.
The results of the research can be used by scientific institutions engaged in research aimed at
creating nanoscale polycrystalline microelectronic layers, methods for modifying functional
structures, and studying fundamental aspects of physical phenomena occurring at the
metal/semiconductor interface if atomic contact of the layers is ensured.
