Sink-effect of nanocavities: Thermodynamic and kinetic approach

Abstract

Sink-effect of nanocavities in a host crystal to metallic impurity atoms is proposed on the basis of the established thermodynamic and kinetic approach at the nanometer scale. The trapping impurity mechanisms of nanocavities are attributed to the thermodynamic contact epitaxy of impurity atoms on the inner surface of nanocavities and the kinetic diffusion flux of impurity atoms pointing to nanocavities. These theoretical results exhibit that the nanocavity in a host crystal as a functional unit could be used to fabricate nanodevices.
