  1. 6. Advanced rear contact design for CIGS solar cells

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jorge Alexandre De Abreu Mafalda; [2019]
    Keywords : CIGS; HfO2; surface passivation; alkali treatment; point contact openings; SCAPS;

    Abstract : The current trend concerning the thinning of solar cell devices is mainly motivated by economic aspects, such as the cost of the used rare-earth elements, and by the requirements of emergent technologies. The introduction of ultra-thin absorber layers results in a reduction of used materials and thus contributes to a more cost-effective and time-efficient production process. READ MORE

  3. 7. Electro-Optical Characterization of Passivated InAsP/InP Quantum Discs-in-Nanowire Heterostructures

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Samareh Kordi Jazi; [2018]
    Keywords : Physics and Astronomy;

    Abstract : Semiconductor nanowires, with their quasi one-dimension geometry, inherently provide strain relaxation for heterogeneous integration and also strong light mode confinement. Nanowire-based photonic devices have also been demonstrated to offer significantly enhanced quantum efficiency, gain and reduced noise. READ MORE

  4. 8. Material characterization of multi-layered Zn-alloy coatings on fasteners : Effects on corrosion resistance, electrical conductivity and friction

    University essay from KTH/Materialvetenskap

    Author : Ante Vallien; [2018]
    Keywords : ZnNi; zinc alloy; multi-layered coating; electrodeposited coating; fasteners; corrosion resistance;

    Abstract : Electroplated zinc-alloy coatings have been used on fasteners in the automotive industry for many years. The coating often consists of three layers: a zinc-alloy layer, a passivation layer and a sealer or top-coat. READ MORE

  5. 9. Time-Resolved Photoluminescence Studies of InGaP Nanowires for Improving the Internal Quantum Efficiency

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Lert Chayanun; [2017]
    Keywords : Physics and Astronomy;

    Abstract : Semiconductor Nanowires are promising building blocks for advanced optoelectronic devices since their small diameter give rise to quantization effects. The small diameter also makes them susceptible to non-radiative recombination due to surface states. READ MORE

  6. 10. Fabrication and electrical characterization of Ge/GeOx/Al2O3/HfO2 MOS capacitors

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Laura Zurauskaite; [2016]
    Keywords : ;

    Abstract : Continuous scaling of complementary metal oxide semiconductor (CMOS) devices has led to constant increase in device performance. However, as scaling becomes more difficult with every technological node, alternative channel materials that could replace silicon (Si) are being investigated [1]. READ MORE
