    Nyckelord :interface states; thermally stimulated current TSC ; positron annihilation spectroscopy PAS ; silicon carbide SiC ; metal-oxide-semiconductor field-effect transistor MOSFET ; transmission electron microscopy TEM ; deep level transient spectroscopy DLTS ; metal-oxide-semiconductor MOS ; field-effect mobility; capacitance-voltage C-V ;

    Sammanfattning : The interface between silicon dioxide (SiO2) and silicon carbide (SiC) is at the heart of the SiC metal-oxide-semiconductor field-effect (MOSFET) transistor. The technology to produce a high quality SiO2/SiC interface does not exist today, hampering further development of the SiC MOSFET. LÄS MER

  5. 4. Electrochemical and ion transport characterisation of a nanoporous carbon derived from SiC

    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Chemical engineering; Cottrell equation; radial diffusion; chronoamperometry; potential step measurements; microelectrode technique; nanoporous carbon; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : In this doctoral project, a relatively new form of carbon material, with unique narrow pore size distribution around 7 Å and with uniform structure, has been electrochemically characterised using the single particle microelectrode technique. The carbon has been used as electrode material for supercapacitors. LÄS MER

  7. 5. Interaction of C60 with transition metals for thin film applications

    Författare :Lars Norin; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Chemistry; C60; transition metals; fulleride; carbide; epitaxy; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : 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.
