Utilizing Bragg Coherent X-ray Diffraction Imaging to Understand the Role of Anisotropy on the Self-Organization of Gas Bubble Superlattices

This proposal aims to utilize Bragg coherent diffraction imaging (BCDI) at the ID01 beamline to understand the mechanism for self-organization of gas bubbles into superlattices in selected metals. 3D coherent x-ray diffraction patterns will be used to image Gas Bubble Superlattice (GBS) structures and gain quantitative information on the noble gas bubbles in GBS, such as a change in lattice parameter and strain induced in a variety of metals with a combination of isotropic and anisotropic elastic properties and diffusion mechanisms (interstitial atom versus cluster diffusion). The effect of implantation flux, fluence, and temperature on the formation and structure of GBSs within a Fe, W, and Mo host matrices will be investigated to uncover mechanistic insights into the formation process and reveal how host-guest relationships evolve based on structural transformation.
