“…[14] Most of diamond-like chalcogenides, for example, Cu(In,Ga)(S,Se) 2 , [15] are well recognized as promising candidates for thin film solar cells, photovoltaic devices, etc., while little attention has been paid to its TE performance. Although the possibilities of MDLCs to be thermoelectric materials have been considered historically, [16][17][18] their good TE properties at high temperature are not demonstrated due to the difficulties in measuring or synthesizing them. Up to 2009, Pb-free earthabundant Cu 2 ZnSnSe 4 compound with diamond-like structure has been discovered to possess relatively high zT value (∼ 0.9 at 850 K) after being substituted by Cu or In.…”

Thermoelectric (TE) materials have been considered as a strong candidate for recovering the waste heat from industry and vehicles due to the ability to convert heat directly into electricity. Recently, multinary diamond-like chalcogenides (MDLCs), such as CuInTe 2 , Cu 2 SnSe 3 , Cu 3 SbSe 4 , Cu 2 ZnSnSe 4 , etc., are eco-friendly Pb-free TE materials with relatively large Seebeck coefficient and low thermal conductivity and have aroused intensive research as a popular theme in the TE field. In this review, we summarize the TE performance and device development of MDLCs. The features of crystalline and electronic structure are first analyzed, and then the strategies that have emerged to enhance the TE figure of merits of these materials are illustrated in detail. The final part of this review describes the advance in TE device research for MDLCs. In the outlook, the challenges and future directions are also discussed to promote the further development of MDLCs TE materials.

“…3) due to the intrinsic semiconducting behaviour dominating the carrier's conduction. 32,33 In summary, polycrystalline chalcopyrite compound CuInTe 2 has been successfully synthesized. CuInTe 2 posesses high hole mobility and good electrical properties due to the small distortion in the crystal structure.…”

“…Xue et al [7] researched the structural, elastic and thermoelectric properties of CuGaTe 2 and CuInTe 2 by density functional theory (DFT). They pointed out that both CuGaTe 2 and CuInTe 2 are good thermoelectric materials and CuGaTe 2 especially can reach a thermoelectric figure of merit of 0.63 at 700 K. Mousa et al [8] measured the electrical conductivity and thermoelectric power of CuInTe 2 in the temperature range of 400 °C-970 °C, and found that the thermoelectric power would change from positive in the solid phases to negative in the liquid phases above the melting point.…”

CuInTe 2 chalcopyrite compound is widely used in the fields of optoelectronics and pyroelectricity, and doping atoms can further improve the physical properties of the CuInTe 2 compound. For all we know, this is the first time that the elastic behaviors and lattice dynamical properties of Ag-doped CuInTe 2 compounds with the tetragonal system are determined theoretically. The elastic, lattice dynamical and thermal properties of Cu 1−x Ag x InTe 2 (x=0, 0.25, 0.5, 0.75 and 1) compounds have been investigated by using density functional theory. The obtained elastic constants of Cu 1−x Ag x InTe 2 compounds indicate that these compounds are mechanically stable and elastic anisotropic. The anisotropy of the {001} plane is more obvious than those of the {100} and {010} planes. Additionally, with increasing Ag doping concentrations, the bulk and shear moduli of Cu 1−x Ag x InTe 2 compounds decrease and their toughness improves. The phonon spectra and density of states reveal that Cu (or Ag) atoms in Cu 1−x Ag x InTe 2 compounds form chemical bonds with Te atoms, and Cu-Te bonds are gradually replaced by Ag-Te bonds with increasing Ag doping concentration. Vibration modes of Cu 1−x Ag x InTe 2 compounds at the G point in the Brillouin zone show that each Cu 1−x Ag x InTe 2 (x=0 and 1) crystal includes five irreducible representations (A 1 , A 2 , B 1 , B 2 and E). As for Cu 1−x Ag x InTe 2 (x=0.25, 0.5 and 0.75) compounds, each crystal has three irreducible representations (A, B and E). The atomic displacements of several typical phonon modes in CuInTe 2 crystals have been analyzed to deepen the understanding of lattice vibrations in Cu 1−x Ag x InTe 2 compounds. With increasing Ag doping concentration, the Debye temperatures of Cu 1−x Ag x InTe 2 compounds decrease, while their heat capacities increase.
