Tuesday, August 05, 20083:00 PM - 3:30 PMCNLS Conference Room (TA-3, Bldg 1690) Student Seminar Electronic Structure of CdSe Quantum Dots and Ru Complexes Victor V. AlbertUniversity of Florida, T-12, and CNLS We have attempted to determine the effect of ligands on the electronic structure and phonon-induced relaxation in semiconductor quantum dots (QD). This includes creation and geometry optimization of QD systems passivated by different ligands [P(CH3), HCH3, NH-CH-CH2], pyridines, and others. I am focusing primarily on calculations of the electronic structure and optical spectra of the systems. Binding energies and ionization potentials have also been calculated to analyze the effect of ligands on the opt-electronic properties of the QDs.
