“…For example, a dispersed profile with a long tail appears in silicon when irradiated with light ions along the channeling direction. [33] Similar dispersed multimaximum distributions were found in molecular dynamic (MD) simulations of 0.1-5 keV N and Si-ion implantations in diamond along channeling directions. [34] For comparison, our experimental observations of defect distributions in optical image and confocal Raman spectroscopy mapping are well confined and fairly narrow.…”

Comprehending the implantation‐related characteristic quantities of multihigh‐energy proton irradiation of diamond is of significant technological interest for sensing applications, fabrication of 3D photonic crystals, and color centers (e.g., NV− center)‐based quantum computing. Herein, proton‐projected ranges and defect distributions in the (010) plane (Y‐normal plane) of microwave plasma chemical vapor deposition (MPCVD)‐grown diamond irradiated with 0.5–2.0 MeV proton (H+ or molecular normalH2+ ions) in a nonchanneling (near [001], Z‐axis) direction, are experimentally measured via cross‐sectional optical microscopy and high‐resolution confocal Raman spectroscopy mapping. It is found that the projected ranges of the experimental findings and the simulation results indicate good consistencies, whereas there is considerable disagreement between them in regards to longitudinal straggling and lateral straggling. Based on the comparisons and analyses, a clear view of protons implanted in single crystalline diamond in the high‐energy range theoretically and experimentally is obtained.

“…PACS numbers: 79.20.Rf, 34.50.Bw When energetic atomic projectiles collide with a monocrystalline solid target, pronounced effects that depend on the orientation of the crystal with respect to the beam are observed for a variety of interaction processes. This phenomenon is based on a steering of projectiles between atomic strings or atomic planes within the bulk of a crystal and is commonly called "channeling" [1][2][3][4][5][6]. Channeling effects are present if the direction of the incident beam of particles is close to a major crystal axis (low index directions).…”

Neutral Ne atoms with keV energies are scattered under channeling conditions, i.e., at a glancing angle of incidence, from a LiF(001) surface. By means of a time-of-flight method with a pulsed neutral beam, energy distributions for scattered projectiles are obtained. We find for this specific system that the small energy transferred to the crystal lattice during channeling via binary collisions with large impact parameters dominates the dissipation of projectile energy, whereas all other excitations of the solid can be brought to a negligible level.

“…Nonetheless, the electronic effects should be studied in future. To avoid channeling phenomena [21], the high indexes were selected. The supercell and the number of atoms used are presented in Table 1.…”
