    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

  3. 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

  4. 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 :NATURAL SCIENCES; NATURVETENSKAP;

    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

  5. 5. Doping and Density of States Engineering for Organic Thermoelectrics

    Författare :Guangzheng Zuo; Martijn Kemerink; Ergang Wang; Mariano Campoy-Quiles; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Thermoelectric materials can turn temperature differences directly into electricity. To use this to harvest e.g. waste heat with an efficiency that approaches the Carnot efficiency requires a figure of merit ZT larger than 1. LÄS MER
