Abstract Full text About this article

Chalcostibite (CuSbS2) is composed of earth-abundant elements and has a proper band gap (Eg = 1.05 eV) as a thermoelectric (TE) material. Herein, we report the TE properties in the CuSbS2 based composites with a mole ratio of (1-x)CuSbS2-xCu1.8S (x = 0, 0.1, 0.2, 0.3), which were prepared by mechanical alloying (MA) combined with spark plasma sintering (SPS). X-ray diffraction (XRD) and back-scattered electron image (BSE) results indicate that a single phase of CuSbS2 is synthesized at x = 0 and the samples consist of CuSbS2, Cu3SbS4, and Cu12Sb4S13 at 0.1 ≤ x ≤ 0.3. The correlation between the phase structure, microstructure, and TE transport properties of the bulk samples is established. The electrical conductivity increases from 0.14 to 50.66 S·cm-1 at 723 K and at 0 ≤ x ≤ 0.03, while the Seebeck coefficient holds an appropriate value of 190.51 μV·K-1. The highest ZT value of 0.17 is obtained at 723 K and at x = 0.3 owing to the combination of a high PF 183 μW·m-1·K-2 and a low κ 0.8 W·m-1·K-1.

Abstract

Chalcostibite (CuSbS2) is composed of earth-abundant elements and has a proper band gap (Eg = 1.05 eV) as a thermoelectric (TE) material. Herein, we report the TE properties in the CuSbS2 based composites with a mole ratio of (1-x)CuSbS2-xCu1.8S (x = 0, 0.1, 0.2, 0.3), which were prepared by mechanical alloying (MA) combined with spark plasma sintering (SPS). X-ray diffraction (XRD) and back-scattered electron image (BSE) results indicate that a single phase of CuSbS2 is synthesized at x = 0 and the samples consist of CuSbS2, Cu3SbS4, and Cu12Sb4S13 at 0.1 ≤ x ≤ 0.3. The correlation between the phase structure, microstructure, and TE transport properties of the bulk samples is established. The electrical conductivity increases from 0.14 to 50.66 S·cm-1 at 723 K and at 0 ≤ x ≤ 0.03, while the Seebeck coefficient holds an appropriate value of 190.51 μV·K-1. The highest ZT value of 0.17 is obtained at 723 K and at x = 0.3 owing to the combination of a high PF 183 μW·m-1·K-2 and a low κ 0.8 W·m-1·K-1.
