    • Modification of free-volume defects in the GaS2–Ga2S3– CsCl glasses 

      Klym, H.; Calvez, L.; Popov, Anatoli I. (Springer, 2023)
      Modification of free-volume positron trapping defects in the GaS2–Ga2S3–CsCl chalcogenide glasses was studied using positron annihilation lifetime spectroscopy and Doppler broadening of annihilation radiation methods. It ...

    • Structural investigation of crystallized Ge-Ga-Se chalcogenide glasses 

      Klym, H.; Shpotyuk, O.; Karbovnyk, I.; Calvez, L.; Popov, Anatoli I. (Institute of Physics Publishing, 2019)
      Crystallization transformation in the 80GeSe2-20Ga2Se3 chalcogenide glasses caused by annealing at 380 °C during different duration (25, 50, 80 and 100 hours) are studied using X-ray diffraction and atomic force microscopy ...
