    Abstract : Energy consumption in the world has increased continuously due to a growing population and increased energy consumption per capita. Moreover, the largest part of consumed energy still comes from fossil sources which in 2016 was more than 130 PWh. READ MORE

  4. 2. Study the Influence of Quantum Interference on the Electrical Conductance and Thermoelectric Properties of Molecular Junctions : Synthesis and Thermoelectricity

    Author : Hailiang Xu; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular junctions; charge transport; electronic conductance; thermoelectricity; destructive quantum interference; acetylene molecules; Sonogashira coupling; Ti-mediated transformation; porphyrin; MacDonald [2 2] approach; [3 1] method;

    Abstract : This thesis mainly describes our efforts towards the study of the quantum interference of electronic conductance and thermoelectric properties in molecular junctions. Chapter 1 introduces the concepts of the charge transport in single-molecule junctions, include the electrical conductivity and thermopower which are the main parameters to assess the efficiency of the single-molecule junctions.

  5. 3. Thermoelectric Devices with Electronic and Ionic Conducting Polymers

    Author : Zia Ullah; Xavier Crispin; Magnus Berggren; Marisol Martin-Gonzalez; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermoelectricity; conducting polymers; thermoelectric devices;

    Abstract : The energy consumption in the world is continuously growing and the sources of energy are largely dominated by fossil fuels. However, the resources of oil, gas and coal are diminishing in capacity. Moreover the CO2 emissions arising from their combustion is a great concern because it induces climate changes that threaten our habitat. READ MORE

  6. 4. Thermoelectric Phenomena in Quantum Dots

    Author : Sofia Fahlvik Svensson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Fahlvik Svensson; Coulomb blockade; nanowire; thermoelectricity; quantum dot;

    Abstract : Thermoelectricity is being intensively researched as it is believed to hold great promise for applications in power generation and cooling. One way to quantify the electrical power output of a thermoelectric material is the power factor, a function of electrical conductivity and thermopower. READ MORE
