Then the surface of the metal was sprinkled with cobalt atoms.
The energy from the light is essentially trapped onto the two-dimensional wave on the surface of the metal.
Through a quantum mechanical effect called tunneling, a tiny current of electricity flows from the tip to the surface of the metal it is scanning.
A patina treatment mimics the aging process metal undergoes through oxidation, recreating the finish with a chemical dip that gradually changes the surface of the metal.
"The top surface of the metal is now rough, but the bottom surface in contact with the silicon is quite smooth," says Norris.
The depth of all markings required by this section will be measured from the flat surface of the metal and not the peaks or ridges.

Because they couldn't see below the surface of the metal, it was impossible to tell how deeply the laser was melting the layers as each one was applied.
If they are too strong, the intermediate species is too stable to react further, and the surface of the metal becomes virtually blocked for further reaction.
A narrow undercut is made in the surface of the metal with a chisel and the wire forced into the undercut by means of a hammer.
Surface printing comprises those techniques in which the image is printed from the flat surface of the metal, stone, or other material.
