Classical mesoscopic effect in the resistance of point contacts
The mesoscopic effect of the dependence of the point-contact conductance on the spatial distribution
 of the impurities is theoretically studied. It is shown that the resistance dependence on the diameter d
 is not only determined by the electron mean free path lι but also by the ave...

| description | The mesoscopic effect of the dependence of the point-contact conductance on the spatial distribution
of the impurities is theoretically studied. It is shown that the resistance dependence on the diameter d
is not only determined by the electron mean free path lι but also by the average distance between the
impurities. In the case of two types of impurities with different concentrations the mesoscopic effect is
predicted for a dirty point contact (d >> lι) due to the scattering at specific (e.g magnetic) impurities
with a low concentration. Such contacts were numerically modeled tor random distributions of the two
types of impurities.
