  1. 1. Engineering Epitaxial Graphene for Quantum Metrology

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Hans He; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Epitaxial Graphene; Magnetotransport; Quantum Resistance Metrology; Chemical Doping;

    Sammanfattning : Quantum resistance metrology deals both with the precise and accurate measurement of electrical resistance, by utilizing the quantum hall effect (QHE) in two-dimensional electron gases (2DEGs) such as those based on gallium arsenide (GaAs). Due to the unique properties of graphene, and specifically epitaxial graphene grown on silicon carbide (SiC/G), quantum Hall resistance (QHR) standards based on graphene perform better in a wider parameter space (temperature, current and magnetic field) than conventional semiconducting materials.

  2. 2. Molecular Doping of Epigraphene for Device Applications

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Hans He; [2020]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Molecular Doping; Graphene; epitaxial graphene; THz; Metrology; Hall Effect;

    Sammanfattning : Epitaxial graphene grown on silicon carbide, or epigraphene, offers in principle a suitable platform for electronic applications of graphene which require scalable, reproducible, and high-quality material. However, one of the main drawbacks of epigraphene lies in the difficulty in controlling its carrier density, which hinders its usefulness in future applications. LÄS MER

  3. 3. Sport-sort : sorting algorithms and sport tournaments

    Detta är en avhandling från Linköping : Univ., Department of Computer and Information Science

    Författare :Hans Block; [1987]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Arrange a really short, thrilling and fair tournament! Execute parallel sorting in a machine of a new architecture! The author shows how these problems are connected. He designs several new tournament schemes, and analyses them both in theory and in extensive simulations. He uses only elementary mathematical and statistical methods. LÄS MER

  4. 4. Gregor Paulsson och den konsthistoriska tolkningens problem

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Hans Pettersson; [1997]
    Nyckelord :HUMANIORA; HUMANITIES; Art history; art criticism; historiography; creativity; experimental aesthetics; history of interpretation; psychology of art; social history of art; sociology of art; style; Konstvetenskap; HUMANITIES and RELIGION Aesthetic subjects Art; HUMANIORA och RELIGIONSVETENSKAP Estetiska ämnen Konstvetenskap; History Of Art; konstvetenskap;

    Sammanfattning : The core of this thesis is a critical reading of the Swedish art historian Gregor Paulsson's (1889-1977) method of historical interpretation. Initially; Paulsson developed his scholary perspectivefrom the tradition of formalist aesthetics dominating Swedish art history writing in thebeginning of the 20th century. LÄS MER
