    Sammanfattning : Molecular electronics is an area of micro/nanoelectronics with a number of farreaching goals and challenges: denser implementation of electronic memory and logic, less expensive manufacturing, smaller or more sensitive measurement devices, selfassembly of devices and systems and, last but not least, exploring new science and applications.In recent years, molecular electronics has expanded into a broader field of molecular-scale electronics, partly because molecular components have to be defined in solid-state contexts via lithography and self-assembly, and effectively become hybrid devices with new and interesting properties.

  5. 4. A Quantum Chemical View of Molecular and Nano-Electronics

    Författare :Jun Jiang; Yi Luo; Jim Greer; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi;

    Sammanfattning : This dissertation presents a generalized quantum chemical approach for electron transport in molecular electronic devices based on Green's function scattering theory. It allows to describe both elastic and inelastic electron transport processes at first principles levels of theory, and to treat devices with metal electrodes either chemically or physically bonded to the molecules on equal footing.
