Temperature dependences of total thermal conductivity and certain thermomagnetic coefficients of (In2Te3)1 − x(Cd0.9Zn0.1Te)x solid solution alloys (x = 0.01 and 0.03) were investigated and phonon scattering mechanisms were established. It was shown that ionized impurity centers and point structural defects are active in heat transfer at low temperatures, and scattering by acoustic and optical phonons dominates at high temperatures. At high temperatures, an additional thermal resistance of the crystal lattice appears in the studied solid solution, leading to a three-phonon scattering mechanism. A change in the thermomagnetic coefficients with temperature indicates a variable mechanism of phonon scattering and the elastic character of electron scattering in (In2Te3)1 − x(Cd0.9Zn0.1Te)x alloys.
The CoSb [Formula: see text]–Sn section of the Co–Sb–Sn ternary system was studied by methods of physicochemical analysis. It is shown that the section is quasi-binary, its phase diagram is of a simple eutectic type, with a limited region of solid solutions based on CoSb[Formula: see text], the boundary of which at room-temperature reaches [Formula: see text] mol% Sn. The temperature dependences of some thermoelectric parameters of (CoSb[Formula: see text])[Formula: see text]Sn[Formula: see text] solid solutions have been studied. The thermodynamic functions of a pure CoSb[Formula: see text] and a solid solution alloy of composition (CoSb[Formula: see text])[Formula: see text]Sn[Formula: see text] are calculated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
