  1. 1. Turbulent and neoclassical transport in tokamak plasmas

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Istvan Pusztai; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermonuclear fusion; tokamaks; microinstabilities; transport analysis; isotope effect; impurity transport; neoclassical transport; transport barriers; turbulent transport;

    Sammanfattning : One of the greatest challenges of thermonuclear fusion is to understand, predict and to some extent control particle and energy transport in fusion plasmas. In the present thesis we consider theoretical and experimental aspects of collisional and turbulent transport in tokamak plasmas. LÄS MER

  2. 2. Quantum electronic transport in low-dimensional semiconductors

    Detta är en avhandling från Solid State Physics, Lund University

    Författare :Heiner Linke; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum transport; two-dimensional electron gas; contact-free characterisation; ballistic transport; mesoscopic; electron billiard; quantum dot; electron-electron interaction; non-linear; phase breaking; Halvledarfysik; Fysicumarkivet A:1997:Linke; non-symmetric conductio; Semiconductory physics; low-dimensional structures;

    Sammanfattning : Electronic transport is studied at low temperatures in two-dimensional electron gases (2DEGs) and in mesoscopic semiconductor microstructures. The method of microwave-detection of the Shubnikov-de Haas effect for the contact-free characterisation of transport properties of 2DEGs is explored using both magnetic-field modulation and light-induced carrier modulation.

  4. 4. Electron transport in microbial chlorate respiration

    Detta är en avhandling från Karlstad : Karlstad University

    Författare :Anna Smedja Bäcklund; Karlstads universitet.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; c cytochromes; chlorate reduction; electron transport; c cytokromer; kloratreduktion; elektrontransport; MEDICINE Chemistry Biochemistry; MEDICIN Kemi Biokemi; Kemi; Chemistry;

    Sammanfattning : Several bacterial species are capable to use perchlorate and/or chlorate as an alternative electron acceptor in absence of oxygen. Microbial respiration of oxochlorates is important for biotreatment of effluent from industries where oxochlorates are produced or handled. LÄS MER

  5. 5. Electron Transport in Nanowire Quantum Devices

    Detta är en avhandling från Department of Physics, Lund University

    Författare :Henrik Nilsson; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Spin-orbit coupling; the Kondo effect; the Zeeman effect; Quantum dots; Nanowire memories; Nanowire transistors; InSb; InAs; Nanowires; Electron transport; Andreev reflections; Nanowire RF-SET; Noise in nanowires;

    Sammanfattning : This thesis focuses on electron transport in semiconductor InAs/InP and InSb nanowire quantum devices. However, first the temperature dependence of classical charge transport in InSb nanowire field-effect transistors, FETs, is characterized, using InAs nanowire FETs as a reference. LÄS MER
