    • Creation of glass-characteristic point defects in crystalline SiO2 by 2.5 MeV electrons and by fast neutrons 

      Skuja, Linards; Ollier, Nadège; Kajihara, Koichi; Smits, Krisjanis (Elsevier B.V., 2019)
      Point defects in crystalline SiO2, created by 2.5 MeV electron irradiation at dose below the amorphization threshold or by fast neutrons, were compared by luminescence spectroscopy. Oxygen dangling bonds (“non-bridging ...

    • Discovery of new boron-rich chalcogenides: orthorhombic B6X (X=S, Se) 

      Cherednichenko, Kirill A.; Mukhanov, Vladimir A.; Wang, Zhenhai; Oganov, Artem R.; Kalinko, Aleksandr; Dovgaliuk, Iurii; Solozhenko, Vladimir L. (Scientific Reports, 2020)
      New boron-rich sulfde B6S and selenide B6Se have been discovered by combination of high pressure – high temperature synthesis and ab initio evolutionary crystal structure prediction, and studied by synchrotron X-ray ...

    • Micromechanical Properties of Gd3Ga5O12 Crystals Irradiated with Swift Heavy Ions 

      Aralbayeva, G.M.; Manika, Ilze; Karipbayev, Zh.; Suchikova, Y.; Kovachov, S.; Sugak, D.; Popov, Anatoli I. (Sumy State University, 2023)
      This study investigated the optical absorption and mechanical behavior of Gd3Ga5O12 (GGG) single crystals exposed to fast 84 Kr ions at fluences ranging from 1013 to 1014 ion/cm2. We observed that the optical absorption ...
