Distinctive features of diffusion-controlled radiation defect recombination in stoichiometric magnesium aluminate spinel single crystals and transparent polycrystalline ceramics
(2020)
MgAl2O4 spinel is important optical material for harsh radiation environment and other important applications. The kinetics of thermal annealing of the basic electron (F, F+) and hole (V) centers in stoichiometric MgAl2O4 ...
Kinetic Monte Carlo modeling of Y2O3 nano-cluster formation in radiation resistant matrices
(Elsevier B.V., 2018)
As known, Y2O3 nano-clusters considerably increase radiation resistance of reactor construction materials. To model the nano-cluster formation kinetics, we propose the simplest possible mathematical model and perform kinetic ...
Peculiarities of the diffusion-controlled radiation defect accumulation kinetics under high fluencies
(Elsevier B.V., 2020)
Theory is developed for kinetics of the diffusion-controlled radiation defect accumulation in crystalline solids under high fluencies taking into account recently observed correlation between the defect diffusion energy ...
Kinetics of dimer F2 type center annealing in MgF2 crystals
(Elsevier B.V., 2018)
In this paper, we analyzed experimental annealing kinetics of the primary electronic F centers and dimer F2 centers observed in MgF2 at higher radiation doses and temperatures. The developed phenomenological theory takes ...
Evidence for the formation of two types of oxygen interstitials in neutron-irradiated α-Al2O3 single crystals
(Nature Research, 2021)
Due to unique optical/mechanical properties and significant resistance to harsh radiation environments, corundum (α-Al2O3) is considered as a promising candidate material for windows and diagnostics in forthcoming fusion ...
