A Numerical Study On Dependent Absorption And Scattering By Interacting Nano-sized Particles

Donmezer, Fatma Nazli 01 June 2009 (has links) (PDF)
Understanding and manipulating nanosized particles is crucial for the advancement of nanotechnology research. Dependent light scattering of noble metals can be used to achieve new material responses that can be used in different applications. Dependent light scattering of nanoparticles allows the understanding of orientation and location of closely positioned particles. Besides, dependently scattering metallic particles create significantly enhanced near fields and high absorption rates when excited at their plasmon resonance. It is used for spectrally selective heating and melting of nanosized particles as a nanomanufacturing method. With numerical methods dependent scattering properties of particles can be obtained. In this study, the dependent optical absorption efficiencies of metallic nanoparticles are obtained with the newly developed Integrated Poynting Vector Approach (IPVA). This is used in conjunction with a numerical light scattering solution tool DDSCAT. Results indicate that IPVA and DDSCAT together can be used for the estimation of scattering and absorption of nanoparticles affected by the near field of other particles in their close vicinity. The method is suggested to be suitable for the understanding of physical mechanisms behind dependent scattering prior to experiments that require lots of effort and resources.

Adsorption Of Gold Atoms On Anatase Tio2 (100)-1x1 Surface

Vural, Kivilcim Basak 01 September 2009 (has links) (PDF)
In this work the electronic and structural properties of anatase TiO2 (100) surface and gold adsorption have been investigated by using the first-principles calculations based on density functional theory (DFT). TiO2 is a wide band-gap material and to this effects it finds numerous applications in technology such as, cleaning of water, self-cleaning, coating, solar cells and so on. Primarily, the relation between the surface energy of the anatase (100)-1x1 phase and the TiO2-layers is examined. After an appropriate atomic layer has been chosen according to the stationary state of the TiO2 slab, the adsorption behavior of the Au atom and in the different combinations are searched for both the surface and the surface which is supported by a single Au atom/atoms. It has been observed that a single Au atom tends to adsorb to the surface which has an impurity of Au atom or atoms. Although, the high metal concentration on the surface have increased the strength of the adsorption, it is indicated that the system gains a metallic property which is believed to cause problems in the applications. In addition, the gold clusters of the dimer (Au2) and the trimer (Au3) have been adsorbed on the surface and their behavior on the surface is investigate. It is observed that the interaction between Au atoms in the atomic cluster each other is stronger than that of gold clusters and the surface.
