  1. 21. The Synthesis of Molecular Switches Based Upon Ru(II) Polypyridyl Architecture for Electronic Applications

    Författare :Robert Steen; Simon Dunne; Jan Bergman; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular Electronics; ruthenium; pyridyl complexes; ligand design; ligand synthesis; Organic chemistry; Organisk kemi; Biotechnology Chemical Engineering; bioteknik kemiteknik;

    Sammanfattning : According to the famous axiom known as Moore’s Law the number of transistors that can be etched on a given piece of silicon, and therefore the computing power, will double every 18 to 24 months. For the last 40 years Moore’s prediction has held true as computers have grown more and more powerful. LÄS MER

    Sammanfattning : The earliest landmark in computer technology was construction of the Electronic Numerial Integrator and Computer, ENIAC. Computational switching was performed with vacuum tubes and relays, rather large in size, making this computer rather unwieldy. LÄS MER

  5. 24. Molecular Alligator Clips: A Study of Metal-Molecule Contacts for Molecular Electronics

    Författare :Anton Grigoriev; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nonequilibrium Green s functions; single crystal surfaces; nanostructures; chemisorption; selenium; low index single crystal surface; density functional calculations; organic molecules; sulphur; nonequilibrium electron transport; gold;

    Sammanfattning : In this thesis we present a computational study of the elementary building blocks for molecular electronics, interconnected electronic devices with critical dimensions below 5 nm. Building electronic circuits on that scale requires stable connection between the various parts of the device and to the macroscopic metal electrodes, needed for power supply, support and integration with conventional electronics.

  7. 25. Application of Vibrational Spectroscopy in Organic Electronics

    Författare :Mohammad Javad Jafari; Thomas Ederth; Isak Engquist; Annemarie Pucci; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The rapid technological developments enforce us to live in an increasingly electronic world, and the revolutionary usage of conjugated polymers in electronics in the late 1970s accelerated these developments, based on the unique characteristics of conjugated polymers, such as low cost, easy processing, mechanical flexibility, large-area application and compatibility with a variety of substrates. Organic electronic devices are commercially available in the form of, for example, solar cells, transistors, and organic light-emitting diode (OLED) displays. LÄS MER
