 Abstract: Epitaxial Au thin films with thicknesses of 40–160 nm were grown on (100)-oriented single-crystal NaCl substrates at 300 C by magnetron sputtering. Microstructural analyses revealed that all films possess orthogonal twin networks along the Æ011æ 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.
