Single-crystal alloy thin films (SATFs) are appealing for applications in crystal epitaxy, surface catalysis, and energy conversion. Here, the authors report a method to synthesize wafer-scale binary and ternary SATFs with sub-nanometer roughness, which can be used as substrates for the growth of high-quality graphene single crystals.
