  4. 4. Molecular Electronics - Modeling, Devices and Architecture

    Detta är en avhandling från Chalmers University of Technology

    Författare :Jonas Sköldberg; Chalmers tekniska högskola.; Chalmers University of Technology.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molekylfysik; Molecular physics; Mesoskopisk fysik; Mesoscopic physics; Supraledning; Superconductivity; Icke-linjär dynamik; kaos; Non-linear dynamics; chaos; Elektronik; Electronics; Molecular electronics; hybrid devices; switching networks; threshold logic; reconfigurable logic; self-assembly; nanocell; hysteresis; NDR; memristor;

    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. 5. Flexible and Cellulose-based Organic Electronics

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Jesper Edberg; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; conductive polymers; nanocellulose; nanofibrillated cellulose; composite materials; paper electronics; flexible electronics;

    Sammanfattning : Organic electronics is the study of organic materials with electronic functionality and the applications of such materials. In the 1970s, the discovery that polymers can be made electrically conductive led to an explosion within this field which has continued to grow year by year. LÄS MER
