Irradiation-induced amplification of electric fields at oxide interfaces as revealed by correlative DPC-STEM and DFT
Elizabeth A. Peterson, Dongye Liu, Sean H. Mills +5
Heterointerfaces are ubiquitous in modern devices, found in technologies ranging from microelectronics to structural components for energy applications. Many of these emerging tech…
Fragmenting Diffusion Pathways Confers Extraordinary Radiation Resistance in Refractory Multicomponent Alloys
Bin Xing, Bijun Xie, Wanjuan Zou +11
The accumulation and growth of vacancy clusters under irradiation is a pivotal degradation mode for structural materials in extreme environments. Even tungsten undergoes rapid defe…
The structure and migration of heavily irradiated grain boundaries and dislocations in Ni in the athermal limit
Ian Chesser, Peter M. Derlet, Avanish Mishra +6
The microstructural evolution at and near pre-existing grain boundaries (GBs) and dislocations in materials under high radiation doses is still poorly understood. In this work, we…
Grain boundary metastability controls irradiation resistance in nanocrystalline metals
Osman El-Atwani, Annie K. Barnett, Enrique Martinez +13
Grain boundaries (GBs) in polycrystalline materials are powerful sinks for irradiation defects. While standard theories assume that the sink efficiency of a grain boundary is defin…
