Query: Extraordinary electron transmission through a periodic array of quantum
  dots   We study electron transmission through a periodic array of quantum dots (QD)
sandwiched between doped semiconductor leads. When the Fermi wavelength of
tunneling electron exceeds the array lattice constant, the off-resonant per QD
conductance is enhanced by several orders of magnitude relative to the
single-QD conductance. The physical mechanism of the enhancement is
delocalization of a small fraction of system eigenstates caused by coherent
coupling of QDs via the electron continuum in the leads.
