First-principles study of the electronic stopping power of indium for protons and He ions

The contribution of inner electron excitation to the electronic stopping power of palladium for protons

“…6,7 Ions lose energy gradually as they traverse through materials, and the kinetic energy dissipated by the ions per unit path is defined as the stopping power. 8–14 The ions lose energy mainly through two channels: nuclear stopping power ( S n ) due to elastic collision with the nuclei of the host atoms, and the electronic stopping power ( S e ) due to electronic excitation and ionization of the host electrons. The electronic energy loss of ions is also frequently quantified by the stopping cross section (SCS) ε , which is related to S e by ε = (1/ n ) S e , where n is the atomic number density of the target material.…”

Trajectory-dependent threshold effects of proton stopping power in LiF nanosheets

“…In our simulations, we employed the Δ t × ν ∼ 1.24 × 10 −3 Å method to set the time step for protons of varying velocities, 34,35 which is utilized to guarantee the convergence of the total energy. The computer time required to complete a single rt-TDDFT calculation is 48 hours with four GeForce GTX GPUs.…”

Plasmon Excitation in the Interaction of Slow Singly Charged Argon Ions with Magnesium

“…Charge exchange and electronic excitations in the interaction of slow ions with solids are currently the subject of an intense investigation [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. These processes are important in charge fraction formation, in energy deposition in solids and in several applications such as microscopy and characterization of materials.…”
