Modelling swift heavy ion irradiation in iron

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2009
Abstract Swift heavy ions moving in metals lose most of their energy to inelastic scattering of electrons. The energy deposited in the electronic system is transferred into the atomic system via electron–ion interactions and can lead to melting and creation of new damage and also annealing of pre-existing atomic defects.

The Effect of Swift Heavy Ion Irradiation on Quasicrystals

MRS Proceedings, 2000
AbstractThe effect of pure electronic excitations (by ∼ 835 MeV Kr irradiation) on a stable icosahedral quasicrystal is compared with the effect of electronic excitations combined with the nuclear collisions (by 100 MeV Ni irradiation) occurring in a similar quasicrystal. The critical stopping power was kept at 1300 eV/Å for both the experiments. Under

Swift heavy ion irradiation of amorphous silicon

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2006
Abstract It is well established that swift heavy ion irradiation of glasses leads to irreversible, non-saturating, macroscopic deformation due to the ion hammering effect. Because amorphous silicon is structurally different from the dense metallic silicon liquid, it has not been considered to be a glass and believed to exhibit a melting transition ...

Effect of swift heavy ion irradiation in pyrochlores

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2008
A summary of the results on the radiation stability of pyrochlores (Gd2Zr2O7, Nd2Zr2O7, Gd2Ti2O7) in the electronic stopping regime is given. X-ray diffraction and Raman spectroscopy show a transformation from the ordered pyrochlores (Fd3m) to the anion deficient fluorite (Fm3m) structure in Gd2Zr2O7 or amorphization in Nd2Zr2O7.

Swift heavy ion irradiation of SrTiO

2008
The irradiation of SrTiO3 single crystals with swift heavy ions leads to modifications of the surface. The details of the morphology of these modifications depend strongly on the angle of incidence and can be characterized by atomic force microscopy. At glancing angles, discontinuous chains of nanosized hillocks appear on the surface.

Swift Heavy Ion Irradiation of Amorphous Semiconductors

2016
In this chapter, the interaction of swift heavy ions (SHIs) with amorphous semiconductors is reviewed. While crystalline Si and Ge are insensitive to SHI irradiation, the higher electron-phonon coupling efficiency of their amorphous counterparts can result in ion track formation due to transient melting along the ion path.

Irradiation effect of swift heavy ions on C60 films

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2002
Abstract In this paper we present experimental results on irradiation effects of C 60 films induced by 2.0 GeV Xe 136 ions, delivered by HIRFL at Lanzhou of China. The irradiated C 60 films were analyzed by means of Fourier transform infrared, Raman scattering and X-ray diffraction spectroscopies.
