Did not know that you can now put atoms together like Lego.
The technique is not novel (a decade ago IBM even made a stop-motion film with carbon monoxide molecules to demonstrate it, and more than twenty years before that showed off “IBM In Atoms” as a proof of concept) but it’s an interesting application. The real question in terms of application is, can this technique open the door to higher temperature superconductors?
Strange, I actually know that movie, but never thought this would be possible with different kinds of atoms at the same time. Also from a material point of view I find it fascinating, that different kind of atoms will still stick together and keep the desired structure and not move to form a more energy efficient lattice structure. Is this all happening at temperature close to 0 K?
