Caption

Scanning Tunneling Microscopy image (magnification about 50-million) of a PdGa surface with six dumbbell shaped acetylene-rotor molecules in different rotation states. The to-scale atomic structure of stator (blue-red) and the acetylene-rotor (grey-white in the slightly left-tilted vertical orientation) are shown schematically on the right.
