  1. 11. 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

  3. 12. The impact on the morphology of the active layer from an organic solar cell by using different solvents

    University essay from

    Author : Robbert Schelfhout; [2017]
    Keywords : organic solar cells; polymer solar cells; morphology of active layer; polymer blend; solvent annealing; spin coating; dip coating; time resolved fluorescence; steady state fluorescence; absorption spectroscopy; atomic force microscopy;

    Abstract : The rise in the world population can be correlated with an increase in energy need. Fossil fuels are not going to able to cover this need in energy because not only are they limited, they also have a negative effect on the environment. A reason the more to switch renewable energy. One of the most popular renewable energy source is solar energy. READ MORE

  4. 13. Investigating the stability of a laser-based plasma x-ray source

    University essay from Lunds universitet/Kemisk fysik; Lunds universitet/Fysiska institutionen

    Author : Fredrik Parnefjord Gustafsson; Jens Uhlig; Wilfred Fullagar; Amal El Nahhas; [2016]

    Abstract : The use of laser based plasma x-ray sources (LPXS) has quickly expanded during the past decades due to rapid development of ultrafast laser systems. These sources are used in many research applications such as emission, absorption and particularly time-resolved spectroscopy. READ MORE

  6. 15. Multi-electron correlation spectroscopy of atoms and molecules : Focus on buckminsterfullerene

    University essay from Mjukröntgenfysik; Materialteori

    Author : Delphine Lebrun; [2011]
    Keywords : correlation; C60;

    Abstract : Correlated many-particle dynamics in Coulombic systems is one of today‟s grand challenges in physics. In order to address this task, the electronic structure and electron correlations of multiply ionised systems are studied in this thesis, aiming to obtain information on the dynamics of electron emission processes at unprecedented ease and high resolution.
