Abstract
The influence of the interference of electron waves, which were scattered b
y single impurities on nonlinear quantum conductance of metallic microconst
rictions [as was recently investigated experimentally B. Ludoph rt al., Phy
s. Rev. Lett. 82, 1530 (1999)] is studied theoretically. The dependence of
the interference pattern in the conductance G(V) on the contact diameter an
d the spatial distribution of impurities is analyzed. It is shown that the
amplitude of conductance oscillation is strongly dependent on the position
of impurities inside the constriction.
