Description

Epitaxial Au thin films with thicknesses of 40-160 nm were grown on (1 0 0)-oriented single-crystal NaCl substrates at 300 oC by magnetron sputtering. Microstructural analyses revealed that all films possess orthogonal twin networks along the <0 1 1> directions. The experimentally observed relationship of an increase in twin density with decreasing film thickness is explained by kinematical and thermodynamical modeling. The developed twin model predicts a nanometer-sized width of the twins, in agreement with the experiment
