✦ Synopsis

The temperature dependence of the (\mathrm{Fe}^{3+}-\mathrm{BPR}) in (\mathrm{HgSe}) in the mixed (\mathrm{Fe}^{2+/ 3+}) valence regime is interpreted in terms of lifetime broadening due to resonant scattering: Evaluation of experimental data shows a minimum in the defect density of states at the Fermi level constituting evidence for a Coulomb gap and thus for Wigner crystallization.

We have measured the low temperature resistance in amorphous Si x Ge 1± ±x alloy films. Fitting to the theoretical results, we found two kinds of transport regime in the low temperature transport, variable range hopping type (T À1/4 ) and Coulomb gap type (T À1/2 ), and can determine the crossover t
