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

   Författare :Hailiang Xu; NanoLund: Centre for Nanoscience; []
   Nyckelord :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;

   Sammanfattning : 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.
