Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

Abstract

One of the most significant recent applications of laser ablation is pulsed laser deposition (PLD), a powerful new technology for fabricating unique thin film compositions and structures. Ion-assisted PLD (IAPLD) enhances the capabilities of this technology by providing oriented thin-film structures on amorphous and randomly-ordered polycrystalline substrates. IAPLD is particularly well-suited for fabricating multilayer thin film structures suitable for high temperature superconducting multi-chip modules, We have fabricated such structures on 5.0 μm SiO₂ dielectric layers using IAPLD yttria-stabilized zirconia (YSZ) layers, obtaining critical current densities as high as 3 x 10⁵ A/cm² at 77 K. We have also constructed YBCO/IAPLD-YSZ/SiO₂/YSZ/YBCO/CeO₂/YSZ and YBCO/IAPLD-YSZ/amorphous-YSZ/YBCO/CeO₂/YSZ multilayers. In addition, we are working on IAPLD of oriented CeO₂ layers to improve the YBCO critical current densities
