  1. 6. 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

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

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

    Sammanfattning : 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. LÄS MER

  4. 8. Nitride Thin Films for Thermoelectric Applications : Synthesis, Characterization and Theoretical Predictions

    Författare :Mohammad Amin Gharavi; Per Eklund; Rickard Armiento; Björn Alling; Camille Pallier; Caterina Zanella; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Thermoelectrics is the reversible process which transforms a temperature gradient across a material into an external voltage through a phenomenon known as the Seebeck effect. This has resulted in niche applications such as solid-state cooling for electronic and optoelectronic devices which exclude the need for a coolant or any moving parts and long-lasting, maintenance-free radioisotope thermoelectric generators used for deep-space exploration.

  7. 10. Doping and Density of States Engineering for Organic Thermoelectrics

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