Unglaublich Atom-kleine Gravur auf einer Münze

Ein absolutes Show-off-Video vom Berkeley Lab, das ungemein kleine Dinge auf eine Münze gelasert hat, nur um dann noch kleiner und noch kleiner zu werden (bzw. im Video umgekehrt heraus zoomend und ein bisschen Timelapse gibt es auch noch). Krass!

„In this video, the letters that spell Molecular Foundry were written with a beam of electrons fired at the surface. The smallest feature is 20 nanometers, or roughly 100 atoms. As the video zooms out, you lose sight of Molecular Foundry and see the Berkeley Lab logo, which was written with a beam of charged gallium atoms. As you continue to zoom out, you see an 18 hour timelapse of Abraham Lincoln’s face, again written with gallium atoms. Finally, all of this is done within the Lincoln Memorial side of the penny as it is removed from the focused ion beam.“
