  1. 1. Thermoelectric properties of conducting polymers

    Författare :Olga Bubnova; Xavier Crispin; Magnus Berggren; Alan Kaiser; Linköpings universitet; []
    Nyckelord :Thermoelectric generation; Seebeck coefficient; conducting polymers; thermoelectric efficiency.;

    Sammanfattning : According to different sources, from forty to sixty percent of the overall energy generated in the world today is squandered in waste heat. The existing energy conversion technologies are either close to their efficiency limits or too costly to justify their implementation. LÄS MER

  3. 2. Electrochemical Deposition and Characterization of Thermoelectric Thin Films of Bismuth Telluride and Its Derivatives

    Författare :Yi Ma; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; efficiency; deposition mechanism; thermoelectric properties; Thermoelectric; thin films; bismuth telluride and its derivatives; nano-engineering; electrochemical deposition;

    Sammanfattning : Thermoelectric materials have attracted enormous academic and industrial interest recently due to the fact that they can be used in solid state devices for power generation and cooling applications. It is expected that such thermoelectric applications will eventually contribute to meet the energy challenge in the future if the performance of the current devices can be further promoted through an increase in thermoelectric efficiency of the materials.

  4. 3. Thermoelectric polymer-cellulose composite aerogels

    Författare :Shaobo Han; Xavier Crispin; Simone Fabiano; Rachel Segalman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Thermoelectric materials are scrutinized as energy materials and sensing materials. Indeed, they convert thermal energy into electrical energy. In addition, those materials are actively sensitive to a temperature modification through the generation of an electric signal. LÄS MER

  5. 4. Thermoelectric Phenomena in Quantum Dots

    Författare :Sofia Fahlvik Svensson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Fahlvik Svensson; Coulomb blockade; nanowire; thermoelectricity; quantum dot;

    Sammanfattning : Thermoelectricity is being intensively researched as it is believed to hold great promise for applications in power generation and cooling. One way to quantify the electrical power output of a thermoelectric material is the power factor, a function of electrical conductivity and thermopower. LÄS MER

  7. 5. Synthesis and Characterization of Composite Materials for Thermoelectric Power Generation

    Författare :Richard Heijl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In a thermoelectric material, a temperature difference will give rise to an electric potential that is proportional to the temperature gradient. In a closed circuit, this potential can keep a current flowing as long as the temperature gradient is maintained. LÄS MER
