Imaging material functionality through 3D nanoscale tracking of energy flow

Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Milan Delor, Hannah L. Weaver, QinQin Yu, Naomi S. Ginsberg, | Summary: The ability of energy carriers to move between atoms and molecules underlies biochemical and material function. Understanding and controlling energy flow, however, requires observing it on ultrasmall and ultrafast spatiotemporal scales, where energetic and […]
