The "map" of the electrons: This graph, obtained with the SX-ARPES method, shows bright bands representing the states that electrons occupy in energy/momentum space. The band in the semiconductor gallium nitride (GaN) is clearly separated from the superconducting states (encircled in light blue dashes) in the niobium nitride (NbN). This means that the decisive electrons in the two materials do not interfere with each other.
