Reversible Electron-Beam Patterning of Colloidal Nanoparticles at Fluid Interfaces

Posted by dbos Berkeley, This Week: Nanoscience

Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Jonathan G. Raybin, Ethan J. Dunsworth, Veronica Guo, Naomi S. Ginsberg, | Summary: The directed self-assembly of colloidal nanoparticles (NPs) using external fields guides the formation of sophisticated hierarchical materials but becomes less effective with decreasing particle size. As an alternative, electron-beam-driven assembly offers a potential […]
