Abstract 

During irradiation, energy from a projectile is transferred to both the target’s nuclei and its electrons. Prediction and control of the material’s behavior under irradiation requires understanding its response to the deposition of energy to the atomic and electronic systems, both separately and combined. Using molecular dynamics simulations and the two-temperature model, the speaker investigated the response of materials under irradiation to elastic and inelastic energy loss. The speaker will discuss their coupled effects, effects of the electron-phonon coupling in damage production, and the role of defects in energy dissipation and microstructural alterations in high-energy ion irradiation.
