Atom Nano-pencil
The atom pencil is a device that consists of a transversely laser-cooled and collimated atomic beam that impinges on the nanometer-sized apertures. The aperture translates above a fixed substrate and enables the writing of nanostructures with characteristic sizes down to 50 nm. We have demonstrated the writing properties of the atom pencils fabricated from a track membrane of an asymmetric structure of the hole.[1]
