Molecular dynamics simulations of ion range profiles for heavy ions in light targets

MeV Au ion irradiation in silicon and nanocrystalline zirconia film deposited on silicon substrate

“…One should note that the reduced density used in SRIM is only a quick correction method that has no physical basis. This method for correction of electronic stopping power in SRIM to get better ion range distributions has been demonstrated in other materials, such as SiC [22], and has also been validated by molecular dynamics simulations [23].…”

Damage profiles and ion distribution in Pt-irradiated SiC

“…The predicted Au ion distribution profiles from both methods agree well with each other, and also in agreement with the experimental SIMS results. This work is described in detail elsewhere [33]. The above discussion indicates that the SRIM predictions based on a reduced density is a simple and effective way to compensate the overestimation of the electronic stopping power in the SRIM code and give a better ion range prediction.…”

Charge-state effects on charge transfer of helium ions in gold nanosheet

“…On average, the ability of a material to slow down projectile particles traveling in its interior is characterized by the stopping power [12][13][14][15][16]. Conceptually, the stopping power of a material for a given type of projectile can be divided into two categories depending on the type of particles that compose the material: one the nuclear stopping [12,16,17] at low projectile velocities, in which the projectile particle mainly transfers energy to nuclei without electronic excitations, and another the electronic stopping [13,[17][18][19][20] at high projectile velocities, in which the projectile particle mainly transfers energy to electrons.…”
