Book Synopsis From Thermoelectric Bulk to Nanomaterials by :

Download or read book From Thermoelectric Bulk to Nanomaterials written by . This book was released on 2015. Available in PDF, EPUB and Kindle. Book excerpt: We synthesized Bi2Te3 and CoSb3 based nanomaterials and their thermoelectric, structural, and vibrational properties analyzed to assess and reduce ZT-limiting mechanisms. The same preparation and/or characterization methods were applied in the different materials systems. Single-crystalline, ternary p-type Bi15Sb29Te56, and n-type Bi38Te55Se7 nanowires with power factors comparable to nanostructured bulkmaterialswere prepared by potential-pulsed electrochemical deposition in a nanostructured Al2O3 matrix. p-type Sb2Te3, n-type Bi2Te3, and n-type CoSb3 thin films were grown at room temperature using molecular beam epitaxy and were subsequently annealed at elevated temperatures. It yielded polycrystalline, single phase thin films with optimized charge carrier densities. In CoSb3 thin films the speed of sound could be reduced by filling the cage structure with Yb and alloying with Fe yielded p-type material. Bi2(Te0.91Se0.09)3/SiC and (Bi0.26Sb0.74)2Te3/SiC nanocomposites with low thermal conductivities and ZT values larger than 1 were prepared by spark plasma sintering. Nanostructure, texture, chemical composition, as well as electronic and phononic excitations were investigated by X-ray diffraction, nuclear resonance scattering, inelastic neutron scattering, M ossbauer spectroscopy, and transmission electron microscopy. Furthermore, for Bi2Te3 materials, ab-initio calculations together with equilibrium and non-equilibrium molecular dynamics simulations for point defects yielded their formation energies and their effect on lattice thermal conductivity, respectively. Current advances in thermoelectric Bi2Te3 and CoSb3 based nanomaterials are summarized. Advanced synthesis and characterization methods and theoreticalmodelingwere combined to assess and reduce ZT-limiting mechanisms in these materials.

Available in PDF, EPUB and Kindle. Book excerpt: Document from the year 2014 in the subject Engineering - General, Basics, grade: A, Indian Institute of Technology, Delhi, language: English, abstract: This book documents the efforts towards thermal characterization of templated nanostructures using an infrared (IR) thermography based non-contact technique. One dimensional bismuth telluride Bi2Te3 nanostructures were grown using anodic alumina (AAO) template assisted electrodeposition technique. An infrared thermography based technique was then developed for the in-plane thermal diffusivity measurements of these templated nanocomposites. The thermal diffusivity of the nanowires alone was estimated through comparing the experimental results with the predictions made by a first order lower bound model (FOLBM). A mathematical background of the proposed technique with simulation studies is also reported. Infrared thermography techniques are widely used for non destructive testing (NDT) and evaluation. The application areas are greatly varied: from water entrapment and moisture evaluation of buildings, degradation of EPROM (erasable programmable read only memory) chips and printed circuit boards, defect detection and characterization in turbine blades, medical and veterinary applications such as thermal coronary angiography, humane breast tumors, neuromuscular disorders, public services as forest fire detection and monitoring of traffic roads, to name a few.
