Abstract Amorphous solids are non‐equilibrium states of matter that lack long‐range structural order, and are recognized as key materials in electronics. Although 2D van der Waals materials have been intensively studied in the wide field of mater

We have investigated lattice disordering of cupper oxide (Cu2O) and copper nitride (Cu3N) films induced by high- and low-energy ion impact, knowing that the effects of electronic excitation and elastic collision play roles by these ions, respectively

It has been known that the modification of non-metallic solid materials (oxides, nitrides, etc.), e.g., the formation of tracks, sputtering representing atomic displacement near the surface and lattice disordering are induced by electronic excitation

It has been observed that modifications of non-metallic solids such as sputtering and surface morphology are induced by electronic excitation under high-energy ion impact and that these modifications depend on the charge of incident ions (charge-stat

Swift ion-beam irradiation affects physical properties of materials through radiation damages. In garnet ferrites, one of the best materials for magneto-optics, a heavy ion-beam creates a non-magnetic amorphous defect along the beam track. Because th

We have measured electronic sputtering yields of SiC and KBr by high-energy ions (198 MeV Xe, 99 MeV Xe, 89 MeV Ni, 60 MeV Ar and 55 MeV Cl ions with the equilibrium charge). Employing the carbon-foil collector method, sputtered atoms in the C-foil a

Effects of columnar defects created by 320 MeV Au irradiation on 2H-NbSe2 single crystals with a dose equivalent matching field up to 16 T were studied. Critical temperature is found to be suppressed almost linearly at a rate of 0.07 K/T. At the same

We have measured the electronic sputtering yields of WO3 as a function of the film thickness. WO3 films have been prepared by thermal oxidation of W deposited on MgO substrate and the film thickness is obtained by Rutherford backscattering spectromet
