Vanderbilt researchers part of collaboration that manipulates atomic vibrations and nanomaterials
Oct. 5, 2022—This breakthrough could make it possible to develop customized functionalities to improve on and build new technologies. Electron beams in powerful microscopes have probed materials and nanostructures with atomic-scale resolution, imaged the atomic arrangements and, in combination with theory, unveiled electronic and magnetic properties. Recent developments in microscopy help make it possible to get direct...
Esteemed astrophysics professor Keivan Stassun co-authors NASA study on increasing diversity and inclusion
Oct. 5, 2022—The recent National Academies’ decadal report for astronomy and astrophysics strongly recommended that NASA take serious steps to address the very low numbers of women and underrepresented minorities involved in NASA science,” Stassun said. “In a sense, this new report is part of NASA’s response to that high-level recommendation.

Laser-Driven Petahertz Electron Ratchet Nanobubbles (Luke Bhan, Cody L. Covington, and Kálmán Varga)
Oct. 5, 2022—The ratchet consists of a series of disconnected bubble-shaped nanodiode structures with a sharp tip to induce a large field enhancement. A laser pulse is used to create a plasmon oscillation in the vertical direction, and the shape of the bubble funnels the electrons toward the sharp tip leading to net electron transport in the...
