Phase glides and self-organization of atomically abrupt interfaces out of stochastic disorder in $\alpha$-Ga$_{2}$O$_{3}$

Autor: Azarov, Alexander, Fernández, Javier García, Zhao, Junlei, He, Ru, Park, Ji-Hyeon, Jeon, Dae-Woo, Prytz, Øystein, Djurabekova, Flyura, Kuznetsov, Andrej

Disorder-induced ordering and unprecedentedly high radiation tolerance in $\gamma$-phase of gallium oxide is a recent spectacular discovery at the intersection of the fundamental physics and electronic applications. Importantly, by far, these data we

Unraveling many-body effects in ZnO: Combined study using momentum-resolved electron energy-loss spectroscopy and first-principles calculations

Autor: Leon, Dario A., Elgvin, Cana, Nguyen, Phuong Dan, Prytz, Øystein, Hage, Fredrik S., Berland, Kristian

We present a detailed study of the dielectric response of ZnO using a combination of low-loss momentum-resolved electron energy-loss spectroscopy (EELS) and first-principles calculations at several levels of theory, from the independent particle and

Crystallization Instead of Amorphization in Collision Cascades in Gallium Oxide

Autor: Zhao, Junlei, Fernández, Javier García, Azarov, Alexander, He, Ru, Prytz, Øystein, Nordlund, Kai, Hua, Mengyuan, Djurabekova, Flyura, Kuznetsov, Andrej

Disordering of solids typically leads to amorphization, but polymorph transitions, facilitated by favorable atomic rearrangements, may temporarily help to maintain long-range periodicity in the solid state. In far-from-equilibrium situations, such as

Universal radiation tolerant semiconductor

Autor: Azarov, Alexander, Fernández, Javier García, Zhao, Junlei, Djurabekova, Flyura, He, Huan, He, Ru, Prytz, Øystein, Vines, Lasse, Bektas, Umutcan, Chekhonin, Paul, Klingner, Nico, Hlawacek, Gregor, Kuznetsov, Andrej

Publikováno v: Nature Communications 14, 4855 (2023)

Radiation tolerance is determined as the ability of crystalline materials to withstand the accumulation of the radiation induced disorder. Nevertheless, for sufficiently high fluences, in all by far known semiconductors it ends up with either very hi

Hydrogen-assisted fatigue crack propagation in a pure BCC iron. Part I: Intergranular crack propagation at relatively low stress intensities

Autor: Ogawa Yuhei, Birenis Domas, Matsunaga Hisao, Takakuwa Osamu, Yamabe Junichiro, Prytz Øystein, Thøgersen Annett

Publikováno v: MATEC Web of Conferences, Vol 165, p 03011 (2018)

The role of hydrogen on intergranular (IG) fracture in hydrogen-assisted fatigue crack growth (HAFCG) of a pure iron at low stress intensity was discussed in terms of the microscopic deformation structures near crack propagation paths. The main cause

Hydrogen-assisted fatigue crack propagation in a pure BCC iron. Part II: Accelerated regime manifested by quasi-cleavage fracture at relatively high stress intensity range values

Autor: Birenis Domas, Ogawa Yuhei, Matsunaga Hisao, Takakuwa Osamu, Yamabe Junichiro, Prytz Øystein, Thøgersen Annett

Publikováno v: MATEC Web of Conferences, Vol 165, p 03010 (2018)

Hydrogen effect on fatigue performance at relatively high values of stress intensity factor range, ΔK, of pure BCC iron has been studied with a combination of various electron microscopy techniques. Hydrogen-assisted fatigue crack growth rate is man
