So in order to better understand the interactions of Gd and Sb with Bi and design high performance thermoelectric materials, it was important to study the thermochemical properties and the phase equilibria concerning the Gd-Bi-Sb system and to obtain the thermodynamic parameters of the system.

Five compounds were investigated theoretically in this work to demonstrate the variety of electronic properties in the Gd-Sb-based family: GdSb, GdNiSb, Gd 4 Sb 3, GdSbS 2 O, and GdSb 2. The GdSb compound is a semimetal with the topological nonsymmetric electron pocket along the high-symmetry points Γ–X–W, and hole pockets along the L–Γ ...

Mar 1, 2000 · In the framework of our research on the binary compounds of the rare earth metals with the elements of the 15th group, the results obtained in the investigation of the Gd–Sb system are here reported.

Gd-Sb system. The Gd-Sb system was firstly determined in the concentration range 0-60 at% Sb by Gambino [4]. Later, Gerasimov [12] updated all the invariant equilibria temperatures. The whole composition and temperature ranges in the Gd-Sb phase diagram were established by Abdusalyamova et al. [13]. The four intermediate compounds, Gd. 5. Sb. 3 ...

Oct 1, 2007 · The Gd–Sb binary system has been assessed on the basis of a critical literature review of all phase diagram data and thermodynamic properties. A thermodynamic modeling of the Gd–Sb system was therefore conducted and a set of self-consistent thermodynamic parameters was obtained.

Gd-Sb (Gadolinium-Antimony) Phase diagram To investigate the phase equilibria, Abdusalyamova et al. [86Abd1] have applied X-ray diffractography, thermal analysis and metallographic methods. The phase diagram obtained has been redrawn by Massalski [90Mas1]. From there information was taken to construct Fig. 1. Fig. 1. Gd-Sb. Phase diagram ...

May 15, 2023 · Five compounds were investigated theoretically in this work to demonstrate the variety of electronic properties in the Gd-Sb-based family: GdSb, GdNiSb, Gd 4 Sb 3, GdSbS 2 O, and GdSb 2. The GdSb compound is a semimetal with the topological nonsymmetric electron pocket along the high-symmetry points Γ-X-W, and hole pockets along the L-Γ-X path.
