Thermoelectric properties of gold telluride: AuTe2

Thermoelectric properties of Cu1−xPtxFeO2 (0.0≤x≤0.05) delafossite-type transition oxide

“…The lattice constant of Cu 1−x Pt x FeO 2 samples depends on the Pt in content of the x. The lattice distance of CuFeO 2 for the a-axis and the c-axis are obtained and confirmed with the finding of previous works as given 3.0334Å and 17.1598Å, respectively, which agrees with the standard file of ICSD: 01-075-2146 [22,23]. In addition, the Cu 1−x Pt x FeO 2 samples, the c-axis rapidly increase with increasing Pt content of x, while the a-axis length still remains unchanged with increasing the x content.…”

“…Today, thermoelectric materials [1][2][3] have been displayed their potential as alternative sources of energy. The thermoelectric effect refers to a phenomenon whereby a gradient of temperature is converted directly into electrical current and vise versa.…”

“…These conversion mechanisms have advantages of not having moving parts. The performance of the thermoelectric material is determined by the dimensionless figure of merit, ZT = S 2 T/Ä, where T is the absolute temperature, S is the Seebeck coefficient, and Ä are the electrical and thermal conductivity, respectively [3][4][5]. Ideally, the ZT value approaches its optimum value when and S are maximum, and Ä is as small as possible.…”

Syntheses and characterization of two new selenides Ba5Al2Se8 and Ba5Ga2Se8

“…Chalcogenides are an interesting class of materials with amazing structural complexity [1][2][3][4][5][6] and important properties including thermoelectricity [7][8][9][10], magnetic property [11][12][13][14], nonlinear optical property [15,16], photovoltaicity [17], superconductivity [18], and luminescent property [19,20]. In the past years, many ternary chalcogenides in the A/M/Q system (A = alkaline-earth metal; M = Al, Ga, In; Q = S, Se, Te) have been discovered and studied, including the large family of the AM 2 Q 4 compounds [21][22][23][24][25], the A 2 M 2 Q 5 compounds [26], Ba 5 Ga 2 S 8 [27], Ba 4 Ga 2 S 7 [28], Ba 3 Ga 2 S 6 [28], and Mg 5 Al 2 Se 8 [29].…”

Laser ablation generation of clusters from As‐Te mixtures, As‐Te glass nano‐layers and from Au‐As‐Te nano‐composites. Quadrupole ion trap time‐of‐flight mass spectrometry

“…Gold tellurides constitute minerals such as calaverite, krennerite (AuTe 2 ) and montbrayite (Au 2 Te 3 ), and they are good metallic conductors and even superconductors at low temperature. The thermoelectric properties of gold tellurides have been reported . The structures of Au m Te n ( m , n = 1, 2) clusters were studied by ab initio computational methods …”
