Actual scanning tunneling microscopy images of the naphthalocyanine molecule in the "on" and the "off" state. These images illustrate the stability and exact symmetry of the electrical behavior of the molecule between "on" and "off".
Schematic three-dimensional image of a molecular "logic gate" of two naphthalocyanine molecules, which are probed by the tip of the low-temperature scanning tunneling microscope.
