Solvothermal Synthesis, Structure and Optical Property of Nanosized CoSb3 Skutterudite
Binary skutterudite CoSb(3) nanoparticles were synthesized by solvothermal method. The nanostructuring of CoSb(3) material was achieved by the inclusion of various kinds of additives. X-ray diffraction examination indicated the formation of the cubic phase of CoSb(3). Structural analysis by transmission electron microscopy analysis further confirmed the formation of crystalline CoSb(3) nanopart...
متن کاملBrittle Failure Mechanism in Thermoelectric Skutterudite CoSb3
Skutterudites based on CoSb3 have high thermoelectric efficiency, but the low fracture strength is a serious consideration for commercial applications. To understand the origin of the brittleness in CoSb3, we examine the response along various shear and tensile deformations using density functional theory. We find that the Co−Sb bond dominates the ideal strength. Among all the shear and tensile...
متن کاملAtomistic explanation of brittle failure of thermoelectric skutterudite CoSb3
CoSb3 based skutterudite thermoelectric material has superior thermoelectric properties, but the low fracture toughness prevents its widespread commercial application. To determine the origin of its brittle failure, we examined the response of shear deformation in CoSb3 along the most plausible slip system (010)/<100>, using large-scale molecular dynamics simulations. We find that the brittle f...
متن کاملSynthesis, Crystal Structure and Nonlinear Optical Property of RbHgI3
Searching for new nonlinear optical (NLO) crystals to be used in the infrared (IR) region is still a challenge. This paper presents the synthesis, crystal structure and properties of a new halide, RbHgI3. Its non-centrosymmetric single crystal can be grown in solution. In its crystal structure, all the polar [HgI4] groups align in such a way that brings a favorable net polarization. The measure...
متن کاملSOLVOTHERMAL SYNTHESIS AND OPTICAL PROPERTIES OF WURTZITE-TYPE CdS NANORODS
Cadmium sulfide (CdS) nanorods were synthesized by simple solvothermal reactions at 200 C for 12-24 h using Cd(NO3)2·4H2O and NH2CSNH2 as starting materials and (C2H5)2NH as solvent. XRD and TEM analysis show a hexagonal-phase single crystalline CdS nanorods with diameter of 20 nm and length of 100-200 μm. UV-visible absorption of as-prepared CdS nanorods presented an absorption peak of around ...
