1Realizing nearly isotropic thermoelectric properties in 2D-layered SnS nanomaterials through highly symmetric metastable-phase powder precursors显示文摘Metastable materials offer a broad and novel platform for the development of next-generation science and technology.Phase engineering including synthesis of materials with unconventional phases and phase transition of metastable materials has been explored in layered materials but has not tackled their anisotropy issue yet.The high anisotropy in layered materials further adds the cost of orientation screening of materials.Herein,we report the effect of Ag doping on facilitating the formation of metastableπ-cubic phase SnS during the solvothermal synthesis process.On this basis,we construct cubic-to-orthorhombic(CTO)samples and elucidate the intrinsic mechanisms of its nearly isotropic thermoelectric properties by characterizing the texturing information and analyzing the valence charge density calculated by density functional theory(DFT).This work demonstrates a convenient approach to synthesize layered materials with isotropic electrical and thermal transport behaviors through a precursor of metastable phase.Fanshi Wu Junjie Yuan Wenxin Lai Liangwei Fu Biao Xu 2022Nano Research2022,15,8:0
2Lattice Thermal Transport in Double-filled Skutterudites In_(0.1)Yb_yCo_4Sb_(12)显示文摘In order to investigate the phonon scattering mechanisms in double-filled skutterudites, the low-temperature lattice thermal conductivities of In0.1YbyCo4Sb12 were measured and analyzed based on the Debye model. The eingenmode frequencies of In and Yb were obtained from low-temperature specific heat capacity analysis. It is found that filling these two types of guest atoms with different eingenmode frequencies into the voids in skutterudites could introduce strong point defect and resonant scattering to lattice phonons, thus lead to significant decrease in the lattice thermal conductivity.徐薇 彭江英 HE Jian ZHOU Menghan YANG Junyou FU Liangwei 2013Journal of Wuhan University of Technology(Materials Science)2013,28,4:0
