Atomic-level hologram: neat, but no storage breakthrough yet

http://arstechnica.com/science/news/2009/0...through-yet.ars


The scanning-tunneling microscope (STM) has provided scientists and engineers with the ability to directly manipulate individual atoms. That ability has famously allowed engineers to produce the smallest writing that was thought to be possible: individual atoms lined up to spell out, among other things, the name IBM. Now, researchers from Stanford University have one-upped their peers in private industry by manipulating molecules so that they created a hologram based on interference of electron energy states. Using this technique, they created a single hologram that projects Stanford's S and U in the smallest letters ever written.
