  1. 1. Fabricating designed fullerene nanostructures for functional electronic devices

    University dissertation from Umeå : Umeå universitet

    Author : Christian Larsen; Umeå universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic electronics; Organic field-effect transistor; Organic photovoltaics; Fullerene C60; PCBM; Photochemical transformation; Resist-free lithography; C60 Nanorod; Solution processable; nanomaterials; nanomaterial; Physical Chemistry; fysikalisk kemi; fysik; Physics; Materials Science; materialvetenskap;

    Abstract : A long-term goal within the field of organic electronics has been to developflexible and functional devices, which can be processed and patterned withlow-cost and energy-efficient solution-based methods. This thesis presents anumber of functional paths towards the attainment of this goal via thedevelopment and demonstration of novel fabrication and patterningmethods involving the important organic-semiconductor family termedfullerenes.

  2. 2. Photo-polymerization as a tool for engineering the active material in organic field-effect transistors

    University dissertation from Umeå : Print & Media

    Author : Andrzej Dzwilewski; Umeå universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Field-effect transistor; photo-polymerization; PCBM; C60; Fullerene; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; fasta tillståndets fysik; Solid State Physics;

    Abstract : The emergence of organic semiconductors is exciting since it promises to open up for straightforward and low-cost fabrication of a wide range of efficient and novel electronic devices. However, in order for this promise to become reality it is critical that new and functional fabrication techniques are developed. READ MORE

  3. 3. Electron transfer and fragmentation in fullerene collisions

    University dissertation from Stockholm : Fysikum

    Author : Henning Zettergren; Stockholms universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fullerene; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : In this thesis, we present results from detailed gas phase studies of intrinsic properties of fullerenes (C60) and clusters of fullerenes as probed by slow multiply charged (atomic or cluster) ions in combination with coincidence time-of-flight mass spectrometry. We have investigated the structures, stabilities, and the electron mobilities of multiply charged clusters of fullerenes, (C60)nr+ (r=2-5). READ MORE

  4. 4. Interaction of C60 with transition metals for thin film applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lars Norin; Uppsala universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; C60; transition metals; fulleride; carbide; epitaxy; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : The fullerene molecule C60 is known to undergo many different chemical reactions, including intercalation of alkali- and alkaline earth metals. Relatively little is still known about the reaction between transition metals and C60, and the objective of this thesis was therefore-to investigate the chemical interaction between C60 and some group IV-VI transition metals.
