A thermodynamic model of the influence of atomic impurities on the adhesion strength of interfaces

A thermodynamic model of the influence of atomic impurities on the adhesion strength of interfaces A model which describes the influence of point defects on the work of separation of interfaces of solid materials is developed based on the thermodynamic approach. The model is used to analyze the situation where the joined materials contain the point defects in the form of impurity atoms. The dependence of the work of separation of joined solid materials on the concentration of atomic impurities in their bulks is numerically modeled for different temperatures and in a wide region of parameters. The results show that in certain regions of the parameters, it is possible to strengthen or weaken the interface. The interface can also turn out to be in a state where its spontaneous separation is more favorable. These effects can be applied to control the adhesion properties of multilayered systems. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Microelectronics Springer Journals

Abstract

A model which describes the influence of point defects on the work of separation of interfaces of solid materials is developed based on the thermodynamic approach. The model is used to analyze the situation where the joined materials contain the point defects in the form of impurity atoms. The dependence of the work of separation of joined solid materials on the concentration of atomic impurities in their bulks is numerically modeled for different temperatures and in a wide region of parameters. The results show that in certain regions of the parameters, it is possible to strengthen or weaken the interface. The interface can also turn out to be in a state where its spontaneous separation is more favorable. These effects can be applied to control the adhesion properties of multilayered systems.
