Bystroem-Evers compound Ag5 Pb2O6 has been annealed at 500-540 K under flow of electric current which results in a textured structure and anisotropic colossal electric conductivity (> 10^9 ohm-1cm-1) between 210-525 K. The related physical properties are primarly governed by dissociation of Ag from c-axis channels and lattice strains which in turn depend upon electric current., 13 pages, 7 figures

We have found that the doping of Pb3O4 with silver and its treatment in elevated oxygen pressure result in a number of novel metallic phases. The Pb1-xAgxO1+δ phases (0.4 < δ < 0.6; x ≈ 0.1-0.15) prepared at 260-330 °C exhibit electric and magnetic properties compatible with the indication of superconductivity (SC), which appears at Tc ≈ 285 K. SC can be attributed to Ag doped lead sesquioxide Pb2-xAgxO3-y (y ≈ ±0.2).

Deep trap levels in the semi-insulating SI CdZnTe detector material were characterized by simultaneous multiple peak analysis based on thermally stimulated current TSC measurements. In our TSCs that have been published previously electron hole pairs were created through the use of proton beam irradiation. Charge carriers were captured in deep traps and afterward released by thermal emission, which was recorded in the 90– 300 K range. We showed that the obtained TSC spectra could be well fitted with a unique set of 14 different deep traps, which were all simultaneously and completely characterized. The obtained trap data are in good accordance with earlier deep trap characterizations of the other authors obtained on similar SI CdZnTe materials using different methods.
