  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. Characterization of Nanomaterials for Interconnect and Thermal Management in Electronic Packaging

    Author : Si Chen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat dissipation; electronic packaging; nanomaterial; characterization; thermal interface material; solder; thermoelectric.; interconnect; through silicon via;

    Abstract : Electronic packaging, protecting the fragile chip from atmosphere and providing the paths for signal transmission as well as heat dissipation, is one of the most important parts in electronic devices. The cost, dimensions, performance, and reliability of an electronic device therefore strongly depend on its packaging structures and materials. READ MORE

  5. 3. Synthesis of nanoporous Ca3Co4O9 thin films for flexible thermoelectrics

    Author : Binbin Xin; Per Eklund; Biplab Paul; Niclas Solin; Tomas Nyberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : During energy generation, transportation and usage, large amounts of energy are lost as waste heat. With increasing energy consumption and environmental issues, exploiting this waste heat has drawn extensive attention. READ MORE

  6. 4. Consequences of a non-trivial band-structure topology in solids : Investigations of topological surface and interface states

    Author : Magnus H. Berntsen; Oscar Tjernberg; Philip Hofmann; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; spin- and angle-resolved photoelectron spectroscopy; time-of-flight analyzer; laser based light source; topological insulator; topological crystalline insulator; thin films; surface state; interface state; Bi2Se3; Pb1-xSnxSe;

    Abstract : The development and characterization of experimental setups for angle-resolved photoelectron spectroscopy (ARPES) and spin- and angle-resolved photoelectron spectroscopy (SARPES) is described. Subsequently, the two techniques are applied to studies of the electronic band structure in topologically non-trivial materials. READ MORE

  7. 5. Flexible inorganic and hybrid thermoelectric thin films based on layered calcium cobaltate
