The electrons go in two by two : Scanning tunneling microscopy (STM)/spectroscopy (STS), shows the Mo 154 giant wheel cluster to have a unique localization of states within each of the 14 identical compartments forming its necklace‐type structure (see picture). Each compartment contains two delocalized electrons. These states make the system different from conventional quantum dots that have completely free electrons or excitonic states.
