Caption

(Left) A completely isolated NC is studied using an electron beam (EELS), to determine its bandgap energy. (Right) A NC of the same size surrounded by neighbors is similarly probed, for which the measured bandgap energy is different. Hence, there must be a coupling between adjacent NCs in order for them to 'average' their bandgap energies.
