  1. 1. 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.

  3. 2. Optical Properties of Silicon Nanopillar Arrays for Biosensing

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

    Författare :Inese Krasovska; [2014]
    Nyckelord :;

    Sammanfattning : Biosensing is currently a growing research field which is relevant for different applications, for instance in health care. Sensitive and cheap biosensors are required, preferably as simple as possible in their working principle. LÄS MER

  4. 3. 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.

  5. 4. Study of protein adsorption on structured surfaces using ellipsometry

    Kandidat-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Sebastian Ekeroth; [2011]
    Nyckelord :Ellipsometry; FTIR-spectroscopy; protein adsorption; hydrophobicity;

    Sammanfattning : In order to measure the thickness of a protein layer on a structured surface of silicon rubber, we have used ellipsometry and Fourier transform infrared (FTIR)-spectroscopy. The aim was to determine whether this type of measurement method can be used on protein layers or not. LÄS MER

  7. 5. Optical properties of MAX-phase materials

    Magister-uppsats, Tillämpad optik

    Författare :Marcin Rybka; [2010]
    Nyckelord :MAX; spectroscopic ellipsometry; optical properties; dielectric function;

    Sammanfattning :   MAX-phase materials are a new type of material class. These materials are potentiallyt echnologically important as they show unique physical properties due to the combination of metals and ceramics. In this project, spectroscopic ellipsometry in the spectral range of 0.06 eV –6. LÄS MER
