First-Principles Investigation of Thermodynamic and Kinetic Properties in Ti-H System and B2-NiAl Compound: Phase Stability, Point Defect Complexes and Diffusion.
(2009)
The purpose of this thesis is to show the technique of predicting thermodynamic and kinetic properties from first-principles using density functional theory (DFT) calculations, cluster expansion methods and Monte Carlo ...
Pore Characterization of Ultralow-k Dielectric Thin Films Using Positronium Annihilation Spectroscopy.
(2008)
In this thesis, a series of nanoporous ultralow dielectric constant (ULK) thin films fabricated using spin-coating and sacrificial pore generators (degradable porogens embedded in a host matrix) were studied as a function ...
Modeling Defect Mediated Dopant Diffusion in Silicon.
(2009)
The current understanding of dopant diffusion in silicon comes from the synthesis of experimental and computational research. Dopant diffusion is mediated by defects, and the relevant physical phenomena range over many ...
Molecular Dynamics Simulations of Alkane-Functionalized Polyhedral Oligomeric Silsesquioxanes (POSS). Oligomeric Silsesquioxanes (POSS).
(2009)
Polyhedral oligomeric silsesquioxanes (POSS) is an inorganic cubic-shaped molecule with chemical formula R8Si8O12, where R can be hydrogen atoms or complex organic molecules. Due to the nano-size and because it can be ...
Compression of Smart Materials: Squeeze Flow of Electrorheological and Magnetorheological Fluids.
(2008)
Squeeze flow behavior was experimentally tested for Newtonian fluids. The results show that the squeezing force as a function of the gap gives force varies as gap^−2.5 and gap^−4 for constant area and constant volume ...
