Query: Figure of Merit of one-dimensional resonant transmission systems in the
  quantum regime   The figure of merit, ZT, for a one-dimensional conductor displaying a
Lorentzian resonant transmission probability is calculated. The optimum working
conditions for largest ZT values are determined. It is found that, the
resonance energy has to be adjusted to be several resonance widths away from
the Fermi level. Similarly it is better for the temperature to be equal to
several resonance widths. The approximate relationships, which can be a fairly
good guide for designing devices, between different parameters under optimum
working conditions are given.
