Effect of radially heterogeneous band gap collapse on formation of swift heavy ion tracks in Al2O3
Roman Voronkov, Danil Zainutdinov, Nikita Medvedev +1
We estimate the effects of radial heterogeneity in the collapse of the electronic band gap on the damage in Al2O3 after impact of a swift heavy ion decelerated in the electronic st…
Swift heavy ion track formation in SiC films under high-temperature irradiation
D. I. Zainutdinov, A. E. Volkov
It is known that swift heavy ion (SHI) irradiation at temperatures below 1000 K does not cause structural damage in the bulk SiC. However, the effect of the SiC film thicknes…
Multi-temperature atomic ensemble: nonequilibrium evolution after ultrafast electronic excitation
Nikita Medvedev, Alexander E. Volkov
Ultrafast laser radiation or beams of fast charged particles primarily excite the electronic system of a solid driving the target transiently out of thermal equilibrium. Apart from…
Mechanisms of surface nanostructuring of Al2O3 and MgO by grazing incidence irradiation with swift heavy ions
Marko Karlusic, Ruslan A. Rymzhanov, Jacques H. O'Connell +10
We experimentally discovered that Al2O3 and MgO exhibit well-pronounced nanometric modifications on the surfaces when irradiated under grazing incidence with 23 MeV I beam, in cont…
