Experimenting with IBM Research: Measure the charge state of individual atoms

Building off of a previous paper in 2009, where IBM scientists and collaborators demonstrated the ability to measure the charge state of individual atoms using noncontact atomic force microscopy (AFM), they have now taken it a step further, measuring energy levels of single molecules on insulators, for the first time. The research is appearing today in the peer-review journal Nature Nanotechnology.
