According to the Matthiessen rule the residual resistivity of dilute alloys is proportional to the concentration of impurities:
Figure 7.3: Residual resistivity of various copper alloys after Pawlek and
Riecher. On the horizontal axis are the various dopants in order of
increasing atomic number. On the vertical axis, the coefficient 
in
Eq. 7.1 is plotted. The dashed line represents a fit
to the data, assuming that 
, where Z is the deviation
of the atomic number away from copper.
In Figure 7.3 the coefficient is shown for alloys of copper
with various other materials.
Estimate the scattering rate of the electrons, calculate
the residual resistivity, and compare the results to the experiment.
