We have investigated the influence of the relative proportions of glass formers in a series of lithium alumino-borosilicate glasses with respect to electrical conductivity (σ) and glass transition temperature (Tg) as functions of glass structure, as

Solid solutions in the Ba(Pb1−xSrx)O3−z system were prepared by aliovalent substitution of Pb4+ by Sr2+ ions to investigate the effect of cation stoichiometry on thermal and electrical properties as x was varied between 0 and 0.4, in the temperat

The evidence for a Mott–Hubbard type metal–insulator transition (MIT) is presented in the xP2O5− yV2O5− (100− x − y)WO3 glass system (PVW) at a critical concentration of tungsten (W) ions. Electrons contributed by the reduced vanadium (V)

In thermopower measurements, microwires fabricated from as-purchased bulk PbTe exhibits p-type behavior between room temperature and ∼600 K. At higher temperatures, it undergoes majority carrier inversion and exhibits n-type behavior. We report on

We present a unique method for producing continuous PbTe microwires which may be spooled for commercial use, and provide evidence that such wires tend to form single crystals with diameters less than 10 μm. Because PbTe microwires can, potentially,

Calcium cobaltites, especially Ca3Co4O9 with a misfit layered structure, are promising thermoelectric materials due to their suitability for high temperature applications and low densities. The existence of low spin-state electronic configurations fo

In earlier studies on phosphate and tellurite glasses containing vanadium and iron oxides, non-linear variation of physical properties as functions of the ratios of the transition ions (V/V + Fe) were observed. The most striking effect was observed w

DC resistivity, thermopower and optical absorption of xV2O5–(1 − x) As2O3 (0.58 ≤ x ≤ 0.93) glasses have been studied as a function of composition. The transport mechanism in these glasses has been identified to be a combination of hopping of
