Ultrafast Terahertz Response of Epitaxial and Chemical-Vapor-Deposited Graphene and of Germanium and Germanium/Silicon Core/Shell Nanowires.
(2015)
Nanotechnology has recently enjoyed a tremendous interest, and many emerging nanoscale and low-dimensional materials and devices are under active investigation. This dissertation presents research work on the physics of ...
Robustness and Thermophysical Properties of MOF-5: A Prototypical Hydrogen Storage Material.
(2015)
MOF-5 has attracted considerable attention due to its ability to store gaseous fuels at low pressure with high densities. However, low thermal conductivity and limited robustness upon exposure to water and other reactive ...
Systematic Study of the Phase Behavior of f-block Oxides Irradiated with Swift Heavy Ions.
(2015)
Particles with specific energies of ~1 MeV/u or greater interact with matter primarily through the excitation of electrons. Swift heavy ions, with high masses and velocities in this electronic excitation regime, are ...
Emergence of Spatio-Temporal Pattern Formation and Information Processing in the Brain.
(2015)
The spatio-temporal patterns of neuronal activity are thought to underlie cognitive functions, such as our thoughts, perceptions, and emotions. Neurons and glial cells, specifically astrocytes, are interconnected in complex ...
Modeling Morphology Evolution for Nanostructured Electrochemical Systems.
(2015)
In this dissertation, we examine the morphological evolution of two nanostructured electrochemical systems, the growth of anodic alumina and the electrodeposition/electrodissolution of magnesium. These systems are investigated ...
Using Directional Entropic Forces for Target Pattern Design.
(2015)
Designing attributes of a material’s building blocks in order to assemble them into a target structure is a major goal in materials science. In this thesis, I present three works exploring the role of geometry for self-assembly ...
Electron and Nuclear Spin Dynamics and Coupling in InGaAs.
(2015)
This dissertation focuses on the development of an understanding of electron spin transport, dynamics, and coupling to the nuclear spin system in gallium arsenide (GaAs), as well as the measurement techniques brought to ...
Optical and Theoretical Studies of Excitons in Few-Layer Lead Iodide.
(2015)
Optical measurements and first-principles calculations of few-layer lead iodide (PbI2) crystals are presented in this work. Results indicate that the band structure and exciton energies change dramatically from direct-gap ...
Low Dimensional Polariton Systmes in Subwavelength-Grating Based Microcavities.
(2015)
Semiconductor microcavity exciton-polaritons have recently emerged as a unique, open system for studying non-equilibrium quantum order. Macroscopic quantum phenomenon, Bose-Einstein condensation, has been realized and ...
Development & Application of Constant pH Molecular Dynamics (CPHMD ) for Investigating pH-mediated Transient Conformational States and Their Effects on Nucleic Acid & Protein Activity.
(2015)
pH is a ubiquitous regulator of biological activity, with widespread impact ranging from its role in catalysis to carcinogenesis. Traditionally, a combination of biophysical and computational methods are used to measure ...
