• However in most cases m* is not constant

In this case, can use …(1) for the undoped sample

and …(4) for the doped sample

ie two equations with three unknowns, viz.

xJ , KiJ and m*

We can introduce a third equation from the pure dopant phase viz.

(IiJ)0 = KiJ / m J *

and so have three equations in three unknowns.
