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

Multiferroics exhibit intriguing physical properties and in turn promise new device applications - as a result of the coupling between their order parameters. In this review article, we introduce photoemission electron microscopy (PEEM) as a powerful tool to study multiferroicity with the capability of probing the charge, spin and orbital states of a material simultaneously with nanoscale spatial resolution and element sensitivity. Several systematical studies of ferroelectricity, antiferromagnetism, and multiferroicity using PEEM are discussed. In the end, we outline several challenges remaining in multiferroic research, and how PEEM can be employed as an important characterization tool providing critical information to understand the emergent phenomena in multiferroics.
