Germanium Based Nanotubes: Fact Or Fiction?
(Physics, 2008-09-17)
Unlike carbon nanotubes, nanostructures of Ge, a group IV semiconductor, have not been fully explored. In particular, there is limited data available on Germanium-based nanotubes. The aim of this thesis is to explore the ...
A First-principles Study On Bulk CuO: Electronic Structures And Native Point Defects
(Physics, 2007-08-23)
In this thesis, we have performed a first-principles study on strongly correlated monoclinic cupric oxide (CuO) by using the LSDA+U method implemented in the PAW method. Based on the optimized structural parameters, which ...
On The Behavior Of The 5f Electrons
(Physics, 2007-08-23)
Considerable theoretical efforts have been devoted in recent years to studying the electronic and geometric structures and related properties of surfaces to high accuracy. One of the many motivations for this burgeoning ...
Derivation Of Generalized Lorenz Systems To Study The Onset Of Chaos In High Dimension
(Physics, 2007-08-23)
This thesis provides a new method to derive high dimensional generalized Lorenz systems. Lorenz system is a celebrated nonlinear dynamical dissipative system which was originally derived by Lorenz to study chaos in weather ...
Preparation And Characterization Of Hard Magnetic Nanoparticles
(Physics, 2007-08-23)
Hard-magnetic nanoparticles with uniform size distribution have attracted huge attention in the past several years because of their unique magnetic properties and potential for many applications such as high density recording ...
On The Existence And Stability Of Carbon -based Silicon Fullerenes -a Density Functional Theoretic Study
(Physics, 2007-08-23)
The electronic and geometric properties of silicon-carbon fullerene-like nanostructures with two, four, six, twenty and twenty four carbon atoms on the surface of the Si60 cages by substitution, as well as inside the cage ...
First Observation Of Dijet Events With An Antiproton Tag At [square root]s = 1.96 TEV Using The DØ Forward Proton Detector
(Physics, 2007-08-23)
The Forward Proton Detector (FPD) is a new sub-system of the DØ detector, a 5000 ton particle physics detector located at the Fermilab Tevatron proton-antiproton collider. The FPD was implemented for the Tevatron Run II ...
Silicon Carbide At Nanoscale: Finite Single-walled To "infinite" Multi-walled Tubes
(Physics, 2013-03-20)
A systematic ab initio study of silicon carbide (SiC) nanostructures, especially finite single-walled, infinite double- and multi-walled nanotubes and nanocones is presented. Electronic and structural properties of all ...
Selected Studies Of Celestial Dynamics And Habitability Of Extra Solar Planetary Systems
(Physics, 2013-03-20)
Planetary science in various forms has become interwoven into human culture during all of known human history. The need and desire to expand our horizons has brought humans from basic forms of observation to the development ...
Quantum Modeling Of Dark Matter In Galactic Halos
(Physics, 2013-03-20)
Eighty years after its initial discovery, the nature of dark matter remains a mystery. Contrary to observational evidence, simulations of dark matter halos predict cuspy density profiles and an abundant population of dwarf ...
