    Sammanfattning : Understanding the degradation mechanisms of Li-ion batteries is essential to gain insights into battery aging. The primary research area of this thesis is the positive electrode, NMC811. The purpose of the thesis is to understand how low and elevated temperatures affect the aging of NMC811, by considering the effects on resistance. LÄS MER

  4. 3. Current voltage characterization of high-k oxide on InGaAs substrate

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

    Författare :Muhammad Ismail; [2014]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Abstract Metal oxide semiconductor (MOS) capacitor was fabricated on the InGaAs substrate with Al2O3/HfO2 gate oxide. InGaAs is one of the promising candidates for advanced applications which require the lower power supply and high frequency. LÄS MER
