   Abstract : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.

3. 2. On the Properties of a Few Electron-Hole system in a Double One-dimensional Harmonic Trap

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

   Author : Fan Pan; [2012]
   Keywords : Electron-Hole system; Few-body; CI methods; Exciton-like; Double one-dimension; harmonic trap; Physics and Astronomy;

   Abstract : One of the most important concepts in condensed matter physics is that of ``quasi particles''. The exciton is one such quasi particle. In semi-conductors, excitons are formed by the excitation of electrons from valence band to conduction band, which creates holes in the valence band. READ MORE
