Functional equations and a theoretical model of DLTS. (English) Zbl 0848.39005

The author offers an account of an application of the Pexider equation \(C(v+ w)= D(v) C(w)\) and of homogeneous functions of degree \(p\) (if \(p=0\), he calls them just “homogeneous functions”) to deep level transient spectroscopy.
(Note: With every solution \(C\) of author’s equation (11) (essentially the above Pexider equation), also \(KC\) is a solution with any constant \(K\). Thus also \(C(u)= K \exp (-ku)\) (\(K>0\), \(k>0\) arbitrary; the author has \(K=1\)) is a decreasing positive solution. It is easy to see that this is the general such solution).
