A review of radiation enhanced diffusion in perspective materials

Influence of irradiation upon few-layered graphene using electron-beams and gamma-rays

“…In addition, irradiation facilitates atom diffusion, prompting interstitial atoms to diffuse into existing vacancies and so repairing crystal distortions and imperfections. 19 The effects of gamma irradiation upon FLG seen in this study display opposite trends compared with the irradiated graphite previously studied by Li, 12 because the T d for FLG is lower than that of graphite. The finite curvature of FLG gives rise to a drop in T d , which is reflected in the graphitic structure as a strain in the carbon network and an increase in the ability of FLG to reconstruct by saturating dangling bonds.…”

Monte Carlo modeling of sodium in Mercury’s exosphere during the first two MESSENGER flybys

“…Precipitating ions can increase the diffusion rate by creating defects in the lattice structure of surface grains, a process known as ion, or radiation, enhanced diffusion (cf. reviews by Sizmann (1978) and Starostin (2006)). Therefore, the PSD flux on regions of Mercury's surface open to the solar wind can be larger due to the enhanced diffusion of sodium to the surface by precipitating ions, as Sarantos et al (2008Sarantos et al ( , 2010 have demonstrated for the lunar exosphere.…”

Improving the comprehensive performance of strain flexible sensors by electron irradiation and temperature synergy

“…In addition, irradiation enhanced atomic diffusion can also promote the diffusion of interstitial atoms to vacancies or defects, eliminate vacancies and defects, and repair the distortion and incompleteness of crystals. 37 Under the dual effects of annealing and diffusion promoted by irradiation, the interstitial atoms are easily trapped by a large number of vacancies eliminating the defects (Fig. 5(c)).…”
