Exchange effect on the space charge in nanostructure resonances

It is elucidated that, for nanostructures in which the electron states are filled though the energy range of a transmission or reflection peak (quasilevel resonance), the electron pair distribution has a variety of the Fermi exchange hole in which, to a good approximation, just half of the electron pairs contribute to the Coulomb interaction energy. The displacement of current characteristics due to the space-charge interaction should be calculated with this 1/2 factor. © 1996 American Institute of Physics.
