Experiments have demonstrated a rich variety of self-organized nanoscale concentration modulations in physical vapor deposited films of phase-separating binary alloys. However, no comprehensive model capable of predicting the entire spectrum of these self-organized nanostructures as a function of material and processing parameters has yet been developed. We adopt a phase-field approach to numerically investigate the role of substrates, deposition rates, phase fraction and separation kinetics, on the morphological self-structuring in representative binary vapor-deposited alloys. Based on synergies with experimental results, we map out the processing space where the evolution of mixed morphology is favorable. We propose new strategies for morphology control based on insights gained from this 3D numerical investigation.
