Investigations In The Impact Of Visual Cognition And Spatial Ability Of Student Comprehension Of Physics And Space Science
(Physics, 2011-07-14)
Physics and Space Science examine topics that are highly spatial in nature. Students are required to visualize a system, manipulate that system, and then solve a given problem. Doing all of this, simultaneously, can lead ...
A Study Of The Viscous Interaction Between The Solar Wind And Earth's Magnetosphere Using An MHD Simulation
(Physics, 2012-07-25)
The solar wind interacts with Earth's magnetosphere largely through magnetic reconnection and a “viscous-like” interaction that is not fully understood. The ionospheric cross-polar cap potential (ΦPC) component due to ...
Interaction Of The Geomagnetic Field With Northward Interplanetary Magnetic Field
(Physics, 2013-07-22)
The interaction of the solar wind with Earth's magnetic field causes the transfer of momentum and energy from the solar wind to geospace. The study of this interaction is gaining significance as our society is becoming ...
Measurement Of The Spectral Distribution Of The Low Energy Electrons Emitted As A Result Of M₃VV Auger Transitions In Cu(100)
(Physics, 2012-04-11)
Auger Photoelectron Coincidence Spectroscopy (APECS) was used to investigate the physics of the Low Energy Tail (LET) region of the Auger spectrum of a Cu(100) sample. Two Cylindrical Mirror Analyzers (CMAs) were used to ...
First Measurements Of The Low Energy Tail (LET) Down To 0 eV Using Auger Photoelectron Coincidence Spectroscopy (APECS) In Ag (100) And Cu (100)
(Physics, 2011-03-03)
We present the Auger Photoelectron Coincidence Spectroscopy (APECS) measurements of Ag (100) and Cu (100) over a full range of emitted energies from 0 eV to 81eV. The coincidence measurements were successful in separating ...
The Electronic Properties Of Noble Metal Doped Silicon Nanocrystals Using Hybrid Density Functional Theory
(Physics, 2013-07-22)
One of the most challenging issues in semiconductor physics is to engineer band structures for a particular device. Contemporary photovoltaic (PV) and photoelectrochemical (PEC) devices rely on defect energy levels and ...
Predicting A New Quaternary Photocatalyst Suitable For PEC Process To Produce Hydrogen And Determnation of Its Structural, Electronics, And Optical Properties Using Density Functional Theory
(Physics, 2013-07-22)
Our present work represents a comprehensive theoretical and computational research in quest for predicting new photocatalysts suitable for photoelectrochemical process (PEC) to produce hydrogen by splitting water. We predict ...
Synthesis and Characterization of Nanocomposite Scintillators for Radiation Detection
(2016-05-11)
Inorganic single crystal and organic (plastic and liquid) scintillators are commonly used for radiation detection. Inorganic single crystals are efficient and have better energy resolution compared to organic scintillators. ...
LOW DIMENSIONAL SEMICONDUCTING NANOSTRUCTURES: STABILITY, TRENDS AND PROMISES
(2016-05-10)
Systematic studies of low dimensional semiconducting nanostructures have been performed. In particular, silicon-germanium (SiGe) armchair type nanotubes, and both zigzag and armchair type nanoribbons were used to represent ...
A Deep Chandra Study of Galactic Type Ia Supernova Remnant G299.2-2.9
(2017-12-07)
In this thesis we perform a comprehensive analysis of Galactic Type Ia supernova remnant G299.2-2.9. For this study we analyze our deep 628 ks Chandra observation data of G299.2-2.9. G299.2-2.9 has a complex multiple ...
