  1. 1. Electronic Transport in Strained Materials

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Thomas Dziekan; Uppsala universitet.; [2008]
    Keywords : Physics; Conductivity; Strain; Transport; Boltzmann theory; Transition metal; Hydrogen loading; Electronic structure; Density functional theory; Bulk material; Multilayer; Fysik;

    Abstract : In this thesis the conductivity of strained materials has been investigated using density functional theory and a semiclassical transport theory based on the Boltzmann equation.In transition metals trends are reproduced without adjustable parameters. READ MORE

  2. 2. Electronic Transport in Materials

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Velimir Meded; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Electronic Structure; Ab initio; Condensed Matter Theory; Hydrogen; Boltzmann Transport Equation; Magnetism; Alloys; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : Transport properties within the Boltzmann transport equation for metallic multi-layer structures as well as bulk materials, were the prime topic of this work. Ab initio total energy calculations for Hydrogen loaded metallic multi-layers were performed in order to shed some light onto problem of H depleted layers at the interfaces that have been experimentally observed.

  3. 3. Designing Electronic Waybill Solutions for Road Freight Transport

    University dissertation from Karlskrona : Blekinge Tekniska Högskola

    Author : Shoaib Bakhtyar; Blekinge Tekniska Högskola.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Electronic waybill; e-waybill; Intelligent transport system; ITS services; Freight transport;

    Abstract : In freight transportation, a waybill is an important document that contains essential information about a consignment. The focus of this thesis is on a multi-purpose electronic waybill (e-Waybill) service, which can provide the functions of a paper waybill, and which is capable of storing, at least, the information present in a paper waybill.

  4. 4. Material migration in tokamaks Erosion-deposition patterns and transport processes

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Armin Weckmann; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEXTOR; fusion; plasma physics; transport; migration; tracers; tokamak; limiter; divertor; high-Z; ion beam analysis; Rutherford backscattering; Nuclear reaction analysis; Elastic recoil detection analysis; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Controlled thermonuclear fusion may become an attractive future electrical power source. The most promising of all fusion machine concepts is called a tokamak. The fuel, a plasma made of deuterium and tritium, must be confined to enable the fusion process. It is also necessary to protect the wall of tokamaks from erosion by the hot plasma. READ MORE

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

    University dissertation from Solid State Physics, Lund University

    Author : Heiner Linke; Lunds universitet.; Lund University.; [1997]
    Keywords : 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;

    Abstract : 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.
