“…Various different features have been incorporated into the basic BCA scheme since the earliest simulations by Yoshida [103]. A clear distinction exists between models of amorphous targets (see the early work of Oen et al [104,105]) and more computationally demanding treatments of crystalline lattices. In the former case, target ions are generated for collisions with cascade ions based on a random spread around some mean free-flight path.…”

Abstract. Atomistic simulations are a primary means of understanding the damage done to metallic materials by high energy particulate radiation. In many situations the electrons in a target material are known to exert a strong influence on the rate and type of damage. The dynamic exchange of energy between electrons and ions can act to damp the ionic motion, to inhibit the production of defects or to quench in damage, depending on the situation. Finding ways to incorporate these electronic effects into atomistic simulations of radiation damage is a topic of current major interest, driven by materials science challenges in diverse areas such as energy production and device manufacture.In this review, we discuss the range of approaches that have been used to tackle these challenges. We compare augmented classical models of various kinds and consider recent work applying semi-classical techniques to allow the explicit incorporation of quantum mechanical electrons within atomistic simulations of radiation damage. We also outline the body of theoretical work on stopping power and electron-phonon coupling used to inform efforts to incorporate electronic effects in atomistic simulations and to evaluate their performance.

“…The by far most used methods to simulate ion beam analysis (IBA) processes are those based on the binary collision approximation (BCA) [1][2][3][4][5][6][7][8]7,[9][10][11][12][13][14]. In this approach, the passage of the ion is treated as a sequence of independent binary collisions, neglecting possible many-body effects.…”

“…(It is worth noting that molecular dynamics have enabled the direct study of atomic scale dynamics during the ion beam irradiation, and a review of the simulation technique as it pertains to He þ /Ne þ irradiation can be found elsewhere. 8 ) Monte Carlo methods have long been used to simulate the damage and interaction of a variety of energetic particles in matter, such as neutrons 10 and electrons, 11 developed roughly concurrently with early ion Monte Carlo methods (see, e.g., Beeler, Jr., and Besco, 12 and Oen et al 13 ). Possibly, the most well-known ion-solid Monte Carlo code is stopping and range of ions in matter (SRIM).…”

Focused ion beam nanoscale synthesis has emerged as a critical tool for selected area nanofabrication. Helium and neon ion beams from the gas field ion source have recently demonstrated unparalleled resolution among other scanning ion beams. In this review, the authors focus on the nanoscale synthesis applications for these ion species which have been demonstrated to date. The applications and recent work can broadly be grouped into the following categories: (1) Monte Carlo simulations, (2) direct-write milling or sputtering, (3) ion beam lithography, (4) selective ion implantation or defect introduction, and (5) gas-assisted processing. A special emphasis is given toward using He þ and Ne þ for the processing of two dimensional materials, as several groups have demonstrated promising results. Finally, the authors will discuss the future outlook of He þ and Ne þ nanoprocessing techniques and applications.
