Description:
While two types atoms fall
through a standing lightwave to a surface, only one type is affected
by the lightwave. Starting on the left, the three diagrams depict
standing lightwaves channeling dopant atoms into parallel lines, shifted
90 degrees to produce parallel lines that are perpendicular to the
lines of the layer beneath them, and gradually rotating to channel
the dopant in a spiral pattern. |
