      Depth profiles of nanohardness and photoluminescence of F2 and F3 + centers in LiF crystals irradiated with 12 MeV 12C, 56 MeV 40Ar and 34 MeV 84Kr ions at fluences 1010–1015 ions/cm2 have been studied using laser scanning ...

    • Depth profiles of damage creation and hardening in MgO irradiated with GeV heavy ions 

      Manika, Ilze P.; Maniks, Janis J.; Zabels, Roberts; Grants, Rolands; Kuzmin, Alexei; Schwartz, Kurt (Elsevier B.V., 2019)
      The effect of irradiation with GeV heavy ions (U, Au, Bi) on the structure and mechanical properties of MgO single crystals was studied. The methods of nanoindentation, dislocation mobility, optical absorption and ...

    • Formation of dislocations and hardening of LiF under high-dose irradiation with 5–21 MeV 12C ions 

      Zabels, Roberts; Manika, Ilze P.; Schwartz, Kurt; Maniks, Janis J.; Dauletbekova, Alma K.; Grants, Rolands; Baizhumanov, Muratbek K.; Zdorovets, Maxim V. (Springer Verlag, 2017)
      The emergence of dislocations and hardening of LiF crystals irradiated to high doses with 12C ions have been investigated using chemical etching, AFM, nanoindentation, and thermal annealing. At fluences ensuring the ...

    • Formation of dislocations in LiF irradiated with 3He and 4He ions 

      Manika, Ilze P.; Zabels, Roberts; Maniks, Janis J.; Schwartz, Kurt; Grants, Rolands; Krasta, T.; Kuzmin, Alexei (Elsevier B.V., 2018)
      Influence of the irradiation with 13.5 MeV 3He and 5 MeV 4He ions on the micro-structure and mechanical properties of LiF single crystals was studied. The depth profiles of nanoindentation, dislocation mobility, selective ...

    • Hardness and modulus of elasticity of atomic layer deposited Al2O3-ZrO2 nanolaminates and mixtures 

      Jõgiaas, Taivo; Zabels, Roberts; Tarre, Aivar; Tamm, Aile (Elsevier B.V., 2020)
      Atomic layer deposition was used to produce 90–105 nm thick alumina-zirconia mixtures and nanolaminate structures on soda-lime glass substrate. The resultant chemical and structural compositions of the thin films were ...
