Structural changes in thermoelectric SnSe at high pressures.
The crystal structure of the thermoelectric material tin selenide has been investigated with angle-dispersive synchrotron x-ray powder diffraction under hydrostatic pressure up to 27 GPa. With increasing pressure, a continuous evolution of the crystal structure from the GeS type to the higher-symmetry TlI type was observed, with a critical pressure of 10.5(3) GPa. The orthorhombic high-pressure...
متن کاملThermoelectric properties of single-layered SnSe sheet.
Motivated by the recent study of inspiring thermoelectric properties in bulk SnSe [Zhao et al., Nature, 2014, 508, 373] and the experimental synthesis of SnSe sheets [Chen et al., J. Am. Chem. Soc., 2013, 135, 1213], we have carried out systematic calculations for a single-layered SnSe sheet focusing on its stability, electronic structure and thermoelectric properties by using density functiona...

DOI: 10.1002/aenm.201602328 precursors,[4] doping proves challenging for solution-synthesized MC nanostructures.[5] Recently, post-synthesis halide treatment of nanocrystals in solution has been developed which involves switching halogens for long chain surfactant molecules absorbed on the surface.[2,6] In fact, sorption of halogens can be realized as part of a one-pot synthesis using metal hal...
متن کاملNanoscale clusters in the high performance thermoelectric AgPbmSbTem+2
The local structure of the AgPbmSbTem+2 series of thermoelectric materials has been studied using the atomic pair distribution function PDF method. Three candidate-models were attempted for the structure of this class of materials using either a oneor a two-phase modeling procedure. Combining modeling the PDF with HRTEM data we show that AgPbmSbTem+2 contains nanoscale inclusions with compositi...
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...
