Colloquium Series: Establishing defect-property relationship for low dimensional materials (Dr. Assel Aitkaliyeva, University of Florida)

Tuesday, November 2, 2021 @ 4:00 pm - 5:00 pm

Join us on Zoom for our Colloquium Series. Dr. Assel Aitkaliyeva from the University of Florida will be joining us to present “Establishing defect-property relationship for low dimensional materials.”

Abstract: The radiation response of two-dimensional (2D) dimensional materials deviates dramatically from bulk materials with three-dimensional (3D) bonding networks. In bulk solids, energy deposited by the energetic particles can dissipate in all three-dimensions, unlike in their low dimensional counterparts. The less efficient energy dissipation mechanism in 2D materials can lead to increase in local kinetic energy after the impact. This poses important questions such as: how tolerant are 2D materials to extreme photon and particle fluxes and what are the mechanisms governing their radiation response? In this presentation, we will discuss radiation tolerance of various low dimensional materials, identify defect formation mechanisms in 2D materials, and investigate how defects impact properties of these novel systems. We will demonstrate that defects are not as detrimental to the materials performance as conventional theory dictates and that irradiation can be used to manipulate physical properties of low dimensional materials in a controllable manner.

Biography: Assel Aitkaliyeva is an Assistant Professor of Nuclear Engineering in the Department of Materials Science & Engineering at the University of Florida (UF). Before joining UF in February 2017, she had postdoc and staff scientist appointments at Idaho National Laboratory (INL). She is the recipient of INL Early Career (2015), Fuel Cycle Research and Development (FCRD) Excellence (2016), and US Department of Energy’s (DOE) Early Career Awards (2018). Dr. Aitkaliyeva received her PhD in Materials Science & Engineering (2012) and MS in Nuclear Engineering (2009) at the Texas A&M University. Her research group specializes in 1) establishing defect formation and evolution mechanisms in 2D materials subjected to irradiation, 2) quantifying radiation tolerance of 2D materials, and 3) developing the requisite fundamental knowledge base needed to understand defect-property relationship in this unique class of materials.
