Ternary CuSbSe₂ chalcostibite: facile synthesis, electronic-structure and thermoelectric performance enhancement

Abstract

A single phase CuSbSe2 polycrystalline chalcostibite compound has been facilely synthesized through mechanical alloying for the first time, and the phase evolution has been revealed in detail.

Copper—antimony and copper—bismuth chalcogenides—Research opportunities and review for solar photovoltaics

“…91,92 The elements may also be combined by ball milling at room temperature to produce powder. While for the present family of compounds, this has only been demonstrated for CuSbSe 2 , 88 the method has been used for CdTe and CZTS and may be expected to be general. The elements have been combined by solvothermal synthesis in 1,2-diaminopropane to form CuSbS 2 and CuSbSe 2 , 82 although to date this has only been the subject of a single paper as a method of making bulk materials.…”

“…(ii) CuSbSe 2 : Zhang88 increased ZT by a factor of 1.6 at 623 K, from 0.25 to 0.41 by introducing a small fraction of Cu 3 SbSe 4 which acts to tune the conductivity since it affects both the carrier concentration and mobility. (iii) Cu 3 SbSe 3 : Kirkham89 reports a minimum in thermal Wei90 reports ZT ∼0.25 at 650 K; Liu 84 reports 0.42 at 653 K and Tyagi 91 reports 0.03 at 550 K. Tyagi 92 attributes the low ZT values to low electrical conductivity.…”

Reaction Tailoring for Synthesis of Phase‐Pure Nanocrystals of AgInSe2, Cu3SbSe3 and CuSbSe2

“…Recently, Liu et al have explained synthesis of colloidal Cu 3 SbSe 3 NCs by using highly reactive phosphine free Se precursor and hot injection method . Employing facile novel hot injection method and using triethylene glycol (TEG) as solvent as well as reducing agent, single phase CuSbSe 2 NCs have been synthesized by Hsinag et al Mechanical alloying was employed by Zang et al to synthesize single phase CuSbSe 2 chalcostibite for the first time which showed enhancement in thermoelectric property …”

Thermoelectric performance of SnTe with ZnO carrier compensation, energy filtering, and multiscale phonon scattering

“…[1][2][3][4] The conversion efficiency of a thermoelectric device is determined by the dimensionless thermoelectric figure of merit of the thermoelectric materials involved, ZT=rS 2 T/j, where r, S, j are the electrical conductivity, the Seebeck coefficient and the total thermal conductivity, respectively. [5][6][7][8][9][10] At present, some of the most excellent or highest ZT TE materials aimed for mid-temperature waste heat recovery originate from lead chalcogenides PbX (X=Te, Se and S) and their derivatives, 11 therefore, it is of great significance to develop high-performance and environmental benign new TE materials for mid temperature power generation application.…”
