Enhanced Thermoelectric Properties of Cu3SbSe4 Compounds via Gallium Doping
In this study, the p-type Ga-doped Cu3Sb1−xGaxSe4 compounds were fabricated by melting, annealing, grinding, and spark plasma sintering (SPS). The transport properties of Ga-doped Cu3Sb1−xGaxSe4 compounds were investigated. As Ga content increased, the hole concentration of Cu3Sb1−xGaxSe4 compounds increased, which led to an increase in electrical conductivity. Meanwhile, the Seebeck coefficien...
متن کاملEnhanced Thermoelectric Properties of Polycrystalline SnSe via LaCl3 Doping
LaCl₃ doped polycrystalline SnSe was synthesized by combining mechanical alloying (MA) process with spark plasma sintering (SPS). It is found that the electrical conductivity is enhanced after doping due to the increased carrier concentration and carrier mobility, resulting in optimization of the power factor at 750 K combing with a large Seebeck coefficient over 300 Μvk-1. Meanwhile, all the s...
متن کاملThermoelectric properties and chlorine doping effect of In4Pb0.01Sn0.03Se2.9Clx polycrystalline compounds.
We investigated the thermoelectric properties of Cl-doped polycrystalline compounds In4Pb0.01Sn0.03Se2.9Clx (x = 0.02, 0.04, and 0.06). X-ray diffraction measurement shows a gradual change in lattice volume for x ≤ 0.04 without any impurity phases indicating a systemic change in Cl doping. The Cl doping in the compounds has the effect of increasing carrier concentration and the effective mass o...
متن کاملEnhanced thermoelectric properties of the Zintl phase BaGa2Sb2 via doping with Na or K
Naor K-doped samples of Ba1 x(Na, K)xGa2Sb2 were prepared by ball-milling followed by hot-pressing. The topological analysis of the electron density of BaGa2Sb2 implies a polar covalent nature of the Sb– Ga bonds in which the Sb atoms receive the electrons transferred from Ba rather than the Ga atoms. Successful doping of BaGa2Sb2 with Na or K was confirmed with combined microprobe and X-ray di...
متن کاملEnhanced thermoelectric properties of SnSe polycrystals via texture control.
We present in this manuscript that enhanced thermoelectric performance can be achieved in polycrystalline SnSe prepared by hydrothermal reaction and spark plasma sintering (SPS). X-ray diffraction (XRD) patterns revealed strong orientation along the [l 0 0] direction in bulk samples, which was further confirmed by microstructural observation through transmission electron microscopy (TEM) and fi...
