1 ene 1990 año - IBM logo printed on atomic scale

Descripción:

1990, Don Eigler of IBM in Almaden and his colleagues used a STM to manipulate 35 individual xenon atoms on a nickel surface and formed the letters of IBM logo. The STM was invented to image surfaces at the atomic scale and has been used as a tool with which atoms and molecules can be manipulated to create structures. The tunneling current can be used to selectively break or induce chemical bonds.
