Cumulative X-ray Damage in Bismuth Selenide Examined by Simultaneous TXM and XRD
Sophie E Parsons, Bernard Kozioziemski, Daewoong Nam +21
Bismuth selenide (Bi2Se3) is a topological insulator with potential applications in thermoelectrics, spintronics, and optoelectronics. However, its response to radiation remains po…
Phase transitions of eutectic high entropy alloy AlCoCrFeNi2.1 under shock compression
Sophie E. Parsons, Kento Katagiri, Hangman Chen +31
High entropy alloys (HEAs) are a new class of metals that exhibit unique mechanical performance. Among HEAs, additively manufactured eutectic high entropy alloys (AM-EHEAs) have re…
Pushing the limits of flow strength in diamond
Anirudh Hari, Kento Katagiri, Wanghui Li +34
Extreme pressures and temperatures create conditions that allow even hard and brittle materials to deform plastically. Despite extensive research, the upper limits of flow strength…
X-ray induced grain boundary formation and grain rotation in Bi2Se3
Kento Katagiri, Bernard Kozioziemski, Eric Folsom +24
Optimizing grain boundary characteristics in polycrystalline materials can improve their properties. Many processing methods have been developed for grain boundary manipulation, in…
Computing virtual dark-field X-ray microscopy images of complex discrete dislocation structures from large-scale molecular dynamics simulations
Yifan Wang, Nicolas Bertin, Dayeeta Pal +4
Dark-field X-ray Microscopy (DFXM) is a novel diffraction-based imaging technique that non-destructively maps the local deformation from crystalline defects in bulk materials. Whil…
Comment on "Comments regarding "Transonic dislocation propagation in diamond" by Katagiri, et al. (Science 382, 69-72, 2023)" by Hawreliak, et al. (arXiv:2401.04213)
Kento Katagiri, Tatiana Pikuz, Lichao Fang +24
In their comment (1), Hawreliak et al. claims that our observation of stacking fault formation and transonic dislocation propagation in diamond (2) is not valid as they interpret t…
