  1. 21. InAs and high-k oxides, a scanning tunnelling study of their interfaces

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Mattias Åstrand; [2018]
    Nyckelord :Semiconductor; High-k; Atomic layer deposition; Scanning tunnelling microscopy; Scanning tunnelling spectroscopy; Physics and Astronomy;

    Sammanfattning : In order for semiconductor materials to be suitable for implementation in new and progressive devices they have to be of better electronic characteristics than currently used materials, and maintain these once treated and put into action. It is important to verify that bulk characteristics are not hindered at the surface when a given semiconductor is put in contact with another material due to necessity. LÄS MER

  3. 22. Investigating an electroplating method of Co-Cr alloys : A design of experiment approach to determine the impact of key factors on the electroplating process

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Andreas Nordenström; [2018]
    Nyckelord :design of experiment; electroplating; selective surfaces; Co-Cr; Fractional factorial design; concentrating solar collectors; experimentell design; elektroplätering; solfångare;

    Sammanfattning : Solar energy is increasingly being considered a promising solution to reduce the emissions of CO2 and green house gas. The performance of solar collectors largely depends on the ability to absorb incoming solar radiation with minimal thermal radiation losses. LÄS MER

  4. 23. Creation of thin film CuSbSe2 through closed space vapor transportdeposition

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Malin Eriksen; [2018]
    Nyckelord :CuSbSe; CuSbSe2;

    Sammanfattning : With an increasing demand for fossil-free energy the development of efficient solar cells made from sustainable and abundant materials is needed. A promising group of new absorber materials are the chalcogenide materials, including the chalcostibnite compounds copper antimony selenide, CuSbSe2. LÄS MER

  5. 24. Understanding Sn-seeded InSb nanowire growth

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Författare :Hengfang Zhang; [2017]
    Nyckelord :Science General;

    Sammanfattning : III-Sb semiconductor nanowires have drawn a lot of attention because of their many promising applications, such as thermoelectric generation, low power high efficient electronics and quantum transport. Gold as a catalyst seed particle has been dominating for many years assisting nanowires growth. LÄS MER

  7. 25. Characterization of coated soot particles - Validating a new APM software and using it to design aerosol measurement set-ups

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Jakob Petersson; [2016]
    Nyckelord :Soot; structure; coating; APM; aerosol; Dioctyl Sebacate; Succinic Acid; miniCast; Impinger; electric mobility; effective density.; Physics and Astronomy;

    Sammanfattning : Soot characteristics such as absorbing light are heavily dependent on its structure and interaction with other compounds. By coating soot or collapsing the soot core, the characteristics will be altered which affects its climate forcing, the lung deposition and other interactions with the human upper airways. LÄS MER
