The electrical and thermal properties of SmS in its homogeneity range are investigated within a wide temperature interval. In the range of the existence of the compound the properties are shown to vary from semiconducting to semimetallic ones.
Subject classification: 6 and 8; 14.3; 22 Seiniconductor Institute, Academy of Sciences of the USSR, Leningrad Thermal Conductivity of Gadolinium Monosulphide V. KHUSNUTDINOVA, V. S. OSKOTSPII, I. A. SMIIWOV, and V. M. SERGEEVA The thermal conductivity of gadolinium monosulphidc was measured within the temperature range of 80 to 720 "K. The lattice part of the thermal conductivity ( X L ) mas determined. It is difficult to explain the temperature dependence of q, theoretically taking the phonon scattering by conduction clcctrons into account contrary t o the case of the lanthanum monochalcogenides. The additional lattice thermal resistivity in GdS is attributed to phonon scattering on the paramagnetic statcs of Gd ions in the crystal field. riepaTyp 80 no 720 OK.

Investigations of the electrical properties of Ln3−xX4 compounds (0 ≦ x ≦ 0.33; Ln = = La, Ce, Pr, Nd; X = S, Se, Te) are made in dependence on composition and temperature. These compounds are found to be materials‐analogs. Their conduction mechanisms are determined as function of composition (x).
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.
