Ion-beam mixing induced by atomic and cluster bombardment in the electronic stopping-power regime [PDF]

, 1996
Single crystals of magnesium oxide containing nanoprecipitates of sodium were bombarded with swift ions (∼GeV-Pb, U) or cluster beams (∼20 MeV-C60) to study the phase change induced by electronic processes at high stopping power (≳10 keV/nm).

Making tracks: electronic excitation roles in forming swift heavy ion tracks [PDF]

, 2009
Swift heavy ions cause material modification along their tracks, changes primarily due to their very dense electronic excitation. The available data for threshold stopping powers indicate two main classes of materials.

Peak effect and its evolution with defect structure in YBa2Cu3O7-d thin films at microwave frequencies [PDF]

, 2001
The vortex dynamics in YBa2Cu3O7-d thin films have been studied at microwave frequencies. A pronounced peak in the surface resistance, Rs, is observed in these films at frequencies of 4.88 and 9.55 GHz for magnetic fields varying from 0.2 to 0.8 T.

Ion Charge Influence on the Molecular Structure of Polyethylene Terephthalate Films after Irradiation with Swift Heavy Ions

Crystals, 2020
We report here experimental results investigating the influence of the initial swift heavy ion charge on the structure of polyethylene terephthalate (PET) film after irradiation, using a structurally sensitive X-ray diffraction method.

Ion irradiation-induced foams in antimonide binary alloys: A combination of small energy bandgap with giant surface-to-bulk ratio

Energy Reports, 2020
This is a short review about the ion irradiation-induced foams in antimonide films. III–V semiconductors like InSb and GaSb can be transformed into solid foams with nanometric dimensions upon irradiation with swift heavy ions, increasing significantly ...

Local formation of nitrogen-vacancy centers in diamond by swift heavy ions

, 2014
We exposed nitrogen-implanted diamonds to beams of swift uranium and gold ions (~1 GeV) and find that these irradiations lead directly to the formation of nitrogen vacancy (NV) centers, without thermal annealing.

Tracks and Voids in Amorphous Ge Induced by Swift Heavy-Ion Irradiation [PDF]

Physical Review Letters, 2013
Ion tracks formed in amorphous Ge by swift heavy-ion irradiation have been identified with experiment and modeling to yield unambiguous evidence of tracks in an amorphous semiconductor. Their underdense core and overdense shell result from quenched-in radially outward material flow.
