Abstract Scope |
Designing thin films tailor-made for specific applications is challenging due to complex process-structure-property linkages. A powerful way of rapidly exploring the process-structure-property space is combinatorial deposition, allowing simultaneous fabrication of films with a wide range of compositions and properties. However, extracting insights from these high-throughput depositions to design films with specific properties is also challenging. In this work we combine high-throughput physical vapor deposition, multimodal characterization, and machine learning to identify deposition conditions that result in high hardness, high conductivity Pt-Au alloys. We train autoencoders to capture structural fingerprints in experimental X-ray diffraction patterns, and correlate the learnt fingerprints to electrical conductivity and hardness. Additionally, we correlate process conditions (energy/angle of incoming Pt/Au atoms) with structural fingerprints, and properties, discovering process conditions and compositions that yield properties beyond state-of-the-art nanocrystalline Pt-Au alloys. Our work demonstrates an approach to integrate combinatorial deposition with multimodal data analysis to design advanced thin films. |
