Effects of 3 MeV Proton Irradiation on Superconductivity and CDW in 2H-NbSe₂ Single Crystals

Ion-Selective Scattering Studied Using the Variable-Energy Electron Irradiation in the Ba0.2K0.8Fe2As2 Superconductor

“…Particle irradiation is an alternative way to generate scattering centers, and it has been intensively used to investigate the properties of materials. Depending on the choice of particles, the character of induced scattering centers varies from point-like defects, mostly vacancies (electron irradiation) [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ], to dendritic clusters (proton irradiation) [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ], and to columnar defects (heavy-ion irradiation) [ 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. Furthermore, if the energy of the projectile particles varies, the character of defects generated also changes accordingly since the scattering dynamics significantly vary with the energy [ 39 , 40 ].…”
