High-efficient thermoelectric materials: The case of orthorhombic IV-VI compounds
Improving the thermoelectric efficiency is one of the greatest challenges in materials science. The recent discovery of excellent thermoelectric performance in simple orthorhombic SnSe crystal offers new promise in this prospect [Zhao et al. Nature 508, 373 (2014)]. By calculating the thermoelectric properties of orthorhombic IV-VI compounds GeS,GeSe,SnS, and SnSe based on the first-principles ...
متن کاملTemperature and pressure induced phase transition in IV-VI compounds
2014 The crystal structure of SnS has been investigated as a function of temperature by elastic neutron scattering from 293 K to 1 000 K. SnS undergoes a second order displacive phase transition from the 03B1-phase (B16, Pbnm) to the high temperature 03B2-phase (B33, Cmcm) at 887 K. The mean square displacement of the Sn atom which is isotropic at room temperature becomes increasingly anisotrop...
متن کاملPiezoelectricity in two-dimensional group-III monochalcogenides
KEYWORDS piezoelectricity, two-dimensional (2D) material, monochalcogenide, density functional theory (DFT) calculation ABSTRACT It is found that several layer-phase group-III monochalcogenides, including GaS, GaSe, and InSe, are piezoelectric in their monolayer form. First-principles calculations reveal that the piezoelectric coefficients of monolayer GaS, GaSe, and InSe (2.06, 2.30, and 1.46 ...
متن کاملStructure of liquid SnSe under pressure
Introduction IV-VI compounds are regarded as average group V material. In crystalline group V elements and IV-VI compounds, the Peierls distortion occurs. Strong bonds with short bond length and relatively weak bonds with long bond length coexist in the crystal. Therefore anisotropic contraction of the local structure is expected under pressure [1]. In crystalline SnSe, atoms form two dimension...
متن کاملThermoelectric Performance of Na-Doped GeSe
Recently, hole-doped GeSe materials have been predicted to exhibit extraordinary thermoelectric performance owing largely to extremely low thermal conductivity. However, experimental research on the thermoelectric properties of GeSe has received less attention. Here, we have synthesized polycrystalline Na-doped GeSe compounds, characterized their crystal structure, and measured their thermoelec...
