Postdoctoral Researcher - Autonomous Experimentation for Semiconductor Materials

National Laboratory of the Rockies • Golden, CO

1d • Onsite

About The Position

A postdoctoral research position is available in the Materials Discovery and Development group, focused on autonomous experimentation at the intersection of semiconductor materials research, artificial intelligence methods, and research equipment automation. Our team is developing a next-generation autonomous semiconductor research laboratory as part of the U.S. Department of Energy's METALLIC platform. The successful candidate will support building closed-loop experimental systems that integrate advanced scientific instrumentation, AI-driven decision-making, data infrastructure, and workflow orchestration. The platform will accelerate the discovery of advanced thin film inorganic semiconductor materials that address critical U.S. supply chain challenges, with particular emphasis on semiconductor technologies involving Ga, Ge, Sc and other critical elements and materials. The successful candidate will also have opportunities to contribute to broader autonomous experimentation initiatives across NLR, including the U.S. Department of Energy's Genesis Mission projects aimed to accelerate scientific discovery in wurtzite oxide and nitride wide band gap semiconductor, as well as dielectric, piezoelectric, and ferroelectric materials. As part of these projects, the successful candidate will develop and apply autonomous experimentation approaches across multiple synthesis and characterization instruments, including vacuum deposition systems such as sputtering, pulsed laser deposition, and molecular beam epitaxy (MBE), as well as advanced property characterization tools, such as photoluminescence, profilometry, J-V, C-V, P-E and other electrical measurements, that complement combinatorial structural (XRD) and compositional (XRF) data. This position offers an opportunity to develop and deploy new approaches in AI-driven experimentation, scientific software, robotics, and laboratory automation across a large and rapidly evolving set of experimental instruments.
