Nanoscale Patterning of Chemical Order Introduced by Displacement Cascades in Irradiated Alloys
… ions, MD simulations are used to simulate the disordered zones, which are then incorporated into KMC simulations to reach long irradiation times. These simulations indicate that 1MeV Kr ion irradiation can lead to patterning, whereas 70keV He ion cannot. Experimentally, we propose to use HRTEM …

Quantitative High-angle Annular Dark Field Scanning Transmission To Electron Microscopy For Materials Science
… diffraction (CBED) to measure the degree of chemical order in intermetallic nanoparticles. The experimental and simulation results on the high–angle scattering of 300 keV electrons in crystalline silicon provide a new contribution to the understanding of the temperature dependence of the …

Tailoring charge to spin conversion in novel materials for efficient spintronics
… which cannot be easily modified without invoking chemical or structural changes in the underlying system. This thesis explores materials with nontrivial band structures as potential active spintronics materials and explores a novel method of tunable spin-to-charge conversion, which will provide …

Disorder and nanopatterning in ordered binary alloys: in situ ion irradiation and kinetic Monte Carlo simulation
We study the effects of temperature and disordering rate on the ordered microstructures of real and simulated binary alloys. The behavior of Cu3Au, an alloy with L12 chemical order, is investigated experimentally through in situ electron diffraction and dark-field transmission electron microscopy. …

Magnetic Weyl Semimetals for Spintronic Applications
… develop a series of MTJs with varying degrees of chemical ordering in the Weyl semimetal electrodes and compare their tunneling magnetoresistance (TMR). I find that the TMR is enhanced with the improvement of the chemical ordering in Co₂MnGa. Our results reveal the relationship between the spin …

Structure-property correlations in compositionally complex ferroelectrics
… behavior. Ferroelectrics with switchable polar ordering, for instance, are influenced by local compositional variation, thus requiring an understanding of structure-property relationships. My dissertation work focuses on using atomic scale characterization with an aberration-corrected scanning …

Spin cluster expansion approach to the interplay between short-range order and interstitial atoms in austenitic stainless steels
… Recent studies have highlighted short-range order (SRO) as a key microstructural feature that significantly influences alloy properties. In particular, SRO is found to promote slip planarity, a deformation mode frequently associated with HE. Furthermore, interstitial solutes can interact with …
