  1. 11. Nanoparticles based molecular electronic devices with tunable molecular functionalization shell and gas sensing measurements

    Författare :Omer Sher; Klaus Leifer; Khaled Saoud; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular electronics; gas sensor; hybrid devices; gold nanoparticles; organic molecules; secondary molecular functionalization process;

    Sammanfattning : The idea to use molecules as a basic building block in electronic circuits was developed about 50 years ago when a molecular rectifier was developed, but it has been a challenge for this field to make its way to real-world application. Now, due to the advancement in technologies, the properties of single molecules are better understandable and controllable. LÄS MER

  3. 12. Molecular Engineering of D-π-A Dyes for Dye-Sensitized Solar Cells

    Nyckelord :Organic chemistry; conjugation; polarizability; Group 14 elements; cage compounds; electronic excitations; quantum chemistry; molecular electronics; Organisk kemi;

    Sammanfattning : The basic building blocks in molecular electronics often correspond to conjugated molecules. A compound class consisting of rigid rod-like staffane molecules with the heavier Group 14 elements Si, Ge, Sn and Pb at their bridgehead positions has now been investigated. LÄS MER

  5. 14. Elastic and Inelastic Electron Tunneling in Molecular Devices

    Författare :Mathias Kula; Yi Luo; Alessandro Troisi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular electronics; inelastic electron tunneling spectroscopy; IETS; Green s function; scattering; Theoretical chemistry; Teoretisk kemi;

    Sammanfattning : A theoretical framework for calculating electron transport through molecular junctions is presented. It is based on scattering theory using a Green's function formalism. The model can take both elastic and inelastic scattering into account and treats chemical and physical bonds on equal footing. LÄS MER

  7. 15. Dynamic Effects on Electron Transport in Molecular Electronic Devices

    Författare :Hui Cao; Yi Luo; Colin Lambert; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular electronics; Theoretical chemistry; Teoretisk kemi;

    Sammanfattning : HTML clipboardIn this thesis, dynamic effects on electron transport in molecular electronic devices are presented. Special attention is paid to the dynamics of atomic motions of bridged molecules, thermal motions of surrounding solvents, and many-body electron correlations in molecular junctions. LÄS MER
