Summary

Molecular dynamics simulations reveal how dislocations form in silver (Ag) and copper (Cu) thin films. Film hardness depends on material properties, thickness, and indentation conditions, with hard films enhancing soft substrates.

Main Results:

Misfit dislocation slip is governed by indentation force and lattice mismatches between substrate and film.
Crystal orientation and indentation position significantly impact dislocation structure formation.
Soft films on hard substrates do not improve overall hardness; hard films (>4 nm) on soft substrates enhance hardness.

Conclusions:

Dislocation evolution and mechanical properties of Ag/Cu systems are highly sensitive to structural and external parameters.
Strategic selection of hard films on soft substrates can effectively enhance material hardness.
