  1. 1. Transparent conductive oxides deposited by magnetron sputtering: synthesis and characterization

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Mathias Axelsson; [2019]
    Nyckelord :TCO; AZO; solar cell; magnetron sputtering;

    Sammanfattning : The thesis has dealt with transparent conducting oxide (TCO) materials, with a focus on Al:ZnO and with studies on Sn:In2O3 and ZnO. TCOs are a material group that is used for its properties of being conductive and at the same time transparent. LÄS MER

  3. 2. Investigating the triolein/aqueous interface and Thermomyces lanuginosa lipase activity

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Veronika Tolevska; [2018]
    Nyckelord :Spectroscopic ellipsometry; SAXS; lipase activity; interfacial activation; triolein aqueous interface; physical chemistry; fysikalisk kemi; Chemistry;

    Sammanfattning : The triglyceride/ aqueous interface has an important role in many processes, e.g. lipase activity. Lipase is responsible for the degradation of triglycerides to smaller components, such as fatty acids. LÄS MER

  4. 3. Rear side BSF/emitter patterning of SHJ-IBC solar cells using selective deposition and hydrogen plasma etching of a-Si:H

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Mahmudul Hasan; [2016]
    Nyckelord :;

    Sammanfattning : Silicon heterojunction interdigitated back-contact (SHJ-IBC) solar cells have attracted considerable attention because of their potential to achieve very highly efficiency. However, the back contacting scheme leads to additional fabrication complexity mainly resulting from the formation of interdigitated n- (back surface field (BSF)) and p-type (emitter) hydrogenated amorphous silicon (aSi:H) strips.

  5. 4. Study of the Optical Properties of sp2-Hybridized Boron Nitride

    Master-uppsats, Linköpings universitet/Tillämpad optik

    Författare :Eduardo Antunez de Mayolo; [2014]
    Nyckelord :Spectroscopic ellipsometry; boron nitride; optical properties; materials characterization; III-V nitride semiconductors; cathodoluminescence; electron microscopy; Raman spectroscopy;

    Sammanfattning : Nitride-based semiconductor materials make it possible to fabricate optoelectronic devices that operate in the whole electromagnetic range, since the band gaps of these compounds can be modified by doping. Among these materials, the sp2-hybridized boron nitride has properties that make it a potential candidate for integration in devices operating in the short-wavelength limit, under harsh environment conditions, due to the strength of the B-N bond.

  7. 5. Evaluation of Fullerene-Based Films Ability to Suppress Spontaneous Polymerization

    Master-uppsats, Institutionen för fysik

    Författare :Merve Yesilbas; [2012]
    Nyckelord :fullerene; CdS; CdTe; HNO3; TPP; hydrogen plasma; Raman spectroscopy; spectroscopic ellipsometry; polymerization.;

    Sammanfattning : The aim of the EU-FP7 Marie Curie project is ‘finding fullerene–coated surfaces with maximum photosensitizing activity.’ The effectiveness of fullerene as the singlet oxygen generator decreases in the case of fullerene is condensed to the bulk material form due to polymerization ability.
