  1. 1. Device development for doping evaluation in nanowires using capacitance-voltage measurements

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

    Författare :Emil Nylander; [2016]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis aims to show the prospect of capacitance measurements over nanowire arrays as an evaluation method of the p-doping level in weakly p-doped p-n nanowires. The premise of the method is that there will be a high yield of statistical data regarding the doping level of the nanowires. LÄS MER

  3. 2. InAs MOS capacitors;Fabrication & Characterization

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

    Författare :Felix Vennberg; [2016]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The down scaling of metal-oxide-semiconductor based devices has been halted by the shortcomings of silicon. To enable further miniaturization new materials are required. The proposed replacements include compound III-V semiconductors and high-k oxides, the implementation of which has been difficult. LÄS MER

  4. 3. Influence of Na doping on tunnelling rear contact passivation in Cu(In,Ga)Se2 solar cells

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

    Författare :Markus Sköld; [2016]
    Nyckelord :Sodium; Na; CIGS; solar cells; Passivation; rear contact; Al2O3; tunnelling; tunneling;

    Sammanfattning : In this thesis Cu(In,Ga)Se2 (CIGS) solar cells with different sodiumdoping of the CIGS absorber and varying Al2O3 rear surface passivationlayer thickness have been manufactured and electrically characterised. Baseline samples and samples without passivation were used asreferences for the passivated samples. LÄS MER

  5. 4. Single Crystalline CVD Diamond Based Devices for Power Electronics Applications

    Master-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Ehrnebo Adrian; [2014]
    Nyckelord :;

    Sammanfattning : Chemical vapor deposited single-crystalline diamond has rare material properties such as thermal conductivity five times as high as copper, a wide band gap, a high breakdown field and high carrier mobilities. This makes it a very interesting material for high power, high frequency and high temperature applications. LÄS MER

  7. 5. Characterization of Al2O3 as CIGS surface passivation layer in high-efficiency CIGS solar cells

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

    Författare :Jonathan Joel; [2014]
    Nyckelord :CIGS; Surface Passivation; Thin Film Solar Cells; Al2O3; Capacitance-Voltage; Photoluminescence;

    Sammanfattning : In this thesis, a novel method of reducing the rear surface recombination in copper indium gallium (di) selenide (CIGS) thin film solar cells, using atomic layer deposited (ALD) Al2O3, has been evaluated via qualitative opto-electrical characterization. The idea stems from the silicon (Si) industry, where rear surface passivation layers are used to boost the open-circuit voltage and, hence, the cell efficiency. LÄS MER
