  2. 21. Microstructure aspects of transition metal carbide thin films

    Author : Jun Lu; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; vapour deposition; transition metal carbide; nanocrystallinity; epitaxy; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Transition metal carbides are important refractory materials used in many thin film applications. In this thesis, several transition metal carbides have been deposited using different chemical vapour deposition (CVD) and evaporation processes. In particular, the phase composition and microstructure of these carbide films have been studied. READ MORE

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

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

  5. 23. Studies of Novel Nanostructures by Cross- sectional Scanning Tunneling Microscopy

    Author : Lassana Ouattara; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dilute ferromagnetic semiconductors Superlattices; Cross-sectional scanning tunneling microscopy; Semiconductor nanostructures; Fysik; Physics; Epitaxy; Quantum dots; Nanowires;

    Abstract : This thesis presents structural and morphological studies of semiconductor nanostructures, namely quantum dots, nanowires and a dilute ferromagnetic semiconductor. These nanostructures are investigated on the atomic scale using cross-sectional scanning tunneling microscopy (XSTM). READ MORE

  6. 24. Carbide and MAX-Phase Engineering by Thin Film Synthesis

    Author : Jens-Petter Palmquist; Ulf Jansson; M. Jochen Schneider; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Thin films; microstructure; epitaxy; carbide; WC; MAX-phase; Ti3SiC2; DC magnetron sputtering; PVD; Reciprocal Space Mapping; RSM; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

    Abstract : This thesis reports on the development of low-temperature processes for transition metal carbide and MAX-phase thin film growth. Magnetron sputtering and evaporation, far from thermodynamical equilibrium, have been utilised to engineer the properties of the films by physical and chemical control. READ MORE

  7. 25. Nanowire Heterostructures- Growth, Characterization and Optical Physics

    Author : Niklas Sköld; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nano; Nanowire; photoluminescence; epitaxy; quantum dot;

    Abstract : This thesis describes growth, processing, characterization and photoluminescence (PL) spectroscopy of nanowire heterostructures. The nanowires were made of III-V semiconductor materials and were produced by Au-particle assisted growth. READ MORE
