Research Highlights:
- Developed epitaxial thin film superconductor tapes with engineered nanoscale defects to quadruple performance to world record levels. This technology was successfully transferred to industry and commercialized in 2010. (Royalty-paying license agreement, R&D100 awards, ARPA-E $4M award)
- Created a unique Metal Organic Chemical Vapor Deposition (MOCVD) process and equipment to manufacture thin film superconductor tapes with superior electrical performance, including world records for the highest critical currents (4x better than commercial superconductor tapes). Scaled up technology to 50-meter lengths with novel in-line quality control methods. Enhanced technology for double-sided, defect-tolerant superconductor tapes (DOE Advanced Manufacturing Office $4.5M award, $2M ARPA-E award (2023), $1.5M ARPA-E award (2020), $200,000 CABLE Conductor Manufacturing Prize)
- Demonstrated technology to fabricate ultra-small diameter round superconductor wires with high current densities, using a new symmetric tape architecture that can be wound on 5x smaller diameter than state-of-the-art. Implemented round superconductor wires in magnets being developed for particle accelerators. Founded a startup company to manufacture and commercialize this technology. ($8.15M Small Business Innovation Research (SBIR) awards)
- Developed single crystalline-like semiconductor films exhibiting high mobility (>1100 cm²/Vs) on metal and flexible glass substrates. This technology is now used for low-cost, high-efficiency photovoltaics and high-performance flexible electronics devices (DOE $1.5M award).
- Created a new metrology technique based on 2D X-ray Diffraction for real-time quality control of metal additive manufacturing by Directed Energy Deposition (~$1M NIST award).
- Innovated thin film processing techniques for hetero-epitaxial growth of complex oxide, nitride, silicide, metal, and semiconductor materials on flexible metal substrates.
- Developed a novel crystal growth technique to produce large single-crystalline superconductors with world-record critical current performance in bulk ceramics.
