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

   Author : Yi Ma; Chalmers tekniska högskola; []
   Keywords : 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;

   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.

4. 2. 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

   Abstract : The world’s increasing demand for energy and supplying this energy dominantlyfrom fossil fuels has a major impact on global climate change. Theenergy crisis has gotten more alarming in the recent years which increasedthe motivation for replacing fossil fuels with greener routes for energy harvest. READ MORE

6. 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

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

   Author : Artis Svilans; NanoLund: Centre for Nanoscience; []
   Keywords : 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
