    Sammanfattning : Fossil fuels are still the dominant (ca. 80%) energy source in our society. A significant fraction is used to generate electricity with a heat engine possessing an efficiency of approximately 35%. Therefore, about 65% of fossil fuel energy is wasted in heat. LÄS MER

  4. 3. Scandium Nitride Thin Films for Thermoelectrics

    Författare :Sit Kerdsongpanya; Per Eklund; Björn Alling; Lars Hultman; Gunilla Wingqvist; Heiner Linke; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Thermoelectric devices are one of the promising energy harvesting technologies, since they can convert heat (i.e. a temperature gradient) to electricity. This result leads us to use them to harvest waste heat from heat engines or in power plants to generate usable electricity. LÄS MER

  5. 4. Design of Transition-Metal Nitride Thin Films for Thermoelectrics

    Författare :Sit Kerdsongpanya; Per Eklund; Björn Alling; Gunilla Wingqvist; Lars Hultman; Daniel Gall; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Thermoelectric devices are one of the promising energy harvesting technologies, because of their ability to convert heat (temperature gradient) to electricity by the Seebeck effect. Furthermore, thermoelectric devices can be used for cooling or heating by the inverse effect (Peltier effect). LÄS MER

  7. 5. Synthesis, Electrophoretic Deposition, and Characterization of Nanostructured Thermoelectric Materials

    Författare :Hazal Batili; Muhammet Toprak; Oliver Fenwick; KTH; []
