The Japanese created the "atomic" pen

Scientists from the University of Osaka have created a so-called "atomic" pen, which replaces the silicon atoms on a substrate of tin atoms, writes a blog Pink Tentacle.

For an hour and a half with the help of "atomic" pen researchers succeeded at the site of 2 to 2 nanometra put single atoms "Si" - the chemical symbol of silicon. Experience at room temperature.

According to scientists, smaller inscription can not be done.

"Atomic" pen is based on open before the effect of exchange atoms of silicon atoms in the tin on the approach of scanning probe atomic force microscope to the surface of semiconductor.
