  1. 1. Thermoelectric properties of conducting polymers

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

    Abstract : 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. READ MORE

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

    Author : Yi Ma; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; efficiency; deposition mechanism; thermoelectric properties; Thermoelectric; thin films; bismuth telluride and its derivatives; nano-engineering; electrochemical deposition;

    Abstract : 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.

    Abstract : With the retreating sources of carbon based fuels, thermoelectric materials can play an important role in the future of environmentally friendly power generators. Sb based framework have in some cases shown some promising properties as thermoelectric materials. The physical properties may be modified with doping or incorporation of new elements. READ MORE

  4. 4. Screen Printed Thermoelectric Devices

    Author : Andreas Willfahrt; Xavier Crispin; Werner Zapka; Linköpings universitet; []
    Keywords : Screen printing; thermoelectric generator; Seebeck effect; energy harvesting;

    Abstract : Thermoelectric generators (TEG) directly convert heat energy into electrical energy. The impediments as to why this technology has not yet found extensive application are the low conversion efficiency and high costs per watt. On the one hand, the manufacturing process is a cost factor. READ MORE

  5. 5. Thermoelectric experiments on nanowire-based quantum dots

    Author : Artis Svilans; NanoLund; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quantum dots; Nanowire; Thermoelectric; Maximum power; Efficientcy; Carnot; Kondo effect; Fysicumarkivet A:2018:Svilans;

    Abstract : This thesis experimentally investigates the possibilities of using quantum effects in semiconductor nanostructures for engineering their thermoelectric properties. More specifically, heterostructured InAs/InP nanowires are used to create short InAs quantum dots (QDs) with electronic state structure resembling that found in atoms. READ MORE
