Abstract Scope In the manufacturing engineering for nanofabricated devices, polycrystalline metal thin films are indispensable as electrical resistors and structural elements. However, it is still a daunting task to design such metal films with structural and functional properties (e.g., hardness and resistivity) combined. High-entropy alloy film is considered as a promising candidate material suitable to go further in the simultaneous enhancement of both mechanical and electrical properties of thin film resistor. In this work, the remarkable microalloying (<2.0 at.%) enhancement in several sputtered CoCrFeNi high-entropy alloy films was investigated from a multitechnique approach. High resolution transmission electron microscope characterization shows in particular that there are unusual multifold nanotwins, and nanoscale polytypes. The knowledge of the relationship between structure and properties of such new materials is explored.
