M. Brooks Tellekamp came to NREL in 2018 as a postdoctoral researcher. He studies highly crystalline inorganic materials for applications in LEDs, photovoltaics, power electronics, neuromorphic computing, and electronics operating in harsh conditions. He is interested in understanding and manipulating the integration of dissimilar materials to manipulate and access new functional properties of materials. To accomplish this, he uses tools that enable highly crystalline materials to be integrated with sharp and well defined interfaces—tools such as molecular beam epitaxy, sputtering, and pulsed laser deposition. He is particularly interested in both nitride and oxide materials and hopes to use coupled materials discovery, rapid throughput experiments, and high-quality epitaxial techniques to integrate these materials into next-generation electronics and optoelectronics.
