Ice, one atom thick

Sandia, SciAm, Ice, one atom thickAs water begins to form ice on a cold surface, it first lays down a frozen layer of single atoms.

The picture shows ice one atom thick on a very cold surface.

This is the very first stage of freezing, followed by a thickening formation of layers of ice crystals.

Sandia Labs snapped the first photos of nanometer-thick ice films taken by a scanning tunneling microscope to capture how water molecules deposited an ice film.
