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

The results on the effect of ultraviolet radiation and of the high-frequency plasma discharge on self-assembled formation of the palladium oxide cone-shaped surface nanostructures during thermal oxidation in the oxygen ambient are presented. While for the thermal oxidation growth of the PdO tips takes place at oxidation temperatures T > 750°C only, in the presence of both UV and plasma discharge tip formation has been observed at lower temperatures (450-500°C). Reduction of the tip growth temperature by UV or plasma activation is favorable for proposed technological application of the PdO nanostructures as field emitters in vacuum microelectronics and in the field emitter displays.
