The silicon-vacancy centre in diamond for quantum information processing
Atomic defects in solids offer access to atom-like quantum properties without complex trapping methods while displaying a rich physics due to interactions with their solid-state environment. Such properties have made them an advantageous building block for quantum information processing, in …

Quantitative non-destructive evaluation using laser generated ultrasonic pulses
… laser generated ultrasound for the detection of defects in solids. Ultrasound is generated noncontactively by this method and likewise many of the detection devices used do not require direct coupling to the test pieces, thus acoustic pulses with high frequency components are able to be produced …

Magnetic and Elastic Interactions at Cracks and Interfaces in Ferromagnetic Materials
In addition to being useful for some nondestructive evaluation techniques, interactions between magnetic fields and defects in solids may also alter material properties. To explore this possibility, Maxwell's equations were coupled with a continuum mechanics model for elastic strain to formulate …

Atomic scale diffusion in complex systems from first principles
Transport of point defects controls a variety of materials process such as precipitation, segregation of solutes to grain boundaries and surfaces, and macroscopic properties such as corrosion resistance and ionic conductivity. Therefore, a quantitative prediction of atomic scale transport is …

Novel phase and phase transition behavior of a superionic conductor observed on the nanoscale
This dissertation documents the work performed in the pursuit of a PhD degree in the research group of Prof. Prashant K. Jain at the University of Illinois at Urbana-Champaign. I employed in-situ transmission electron microscopy (TEM) for understanding the ionic structure, vacancy ordering, phase …
